Batista, Getulio Teixeira
Universidade de Taubaté
The mapping of the Permanent Preservation Areas (PPAs) of the municipal district of Santo Antônio do Pinhal, SP, located in an area of great real estate interest in the Mantiqueira Moutains of São Paulo, neighbor of the touristic municipal district of Campos de Jordão, SP, became necessary. The need for producing cartographic documents is to support environmental authorities to establish plans for the preservation of these areas, especially the Permanent Preservation Areas (PPA) established by the Law 4,771/65 and regulated by the Resolutions CONAMA 302 and 303/2002. In that context, this work had as objective, the delimitation of permanent preservation areas (PPA) at the 1:50,000 scale. The analysis and results of the mapping of the permanent preservation areas of the municipal district of Santo Antônio do Pinhal revealed two situations that deserve attention: first, the total area of PPAs corresponds to an area of 7,218ha which is equivalent to 52.2% of the total area of the municipal district. This is very positive for the environmental point of view, however extremely restrictive for land use. The occurrence of PPAs in the class of “Top of Hills” reaches 4,227ha which correspond to 30.7% of the total area of the municipal district. This demonstrates the restrictive character of land use of that PPA class, especially in areas with undulated relief as it is the case of the geomorphological domain known as “Mar de Morros” where the study area is located.

Freitas, José Guilherme
Two agronomic experiments with wheat crop were conducted during the period of May through October of 1999 and 2000 at the experimental site of the University of Taubaté, Taubaté, São Paulo State, Brazil. The objective of this work was to evaluate the effect of different levels of irrigation and nitrogen on grain yield of two wheat cultivars. The work also intended to present the feasibility of this agriculture activity during the winter crop season in the Paraíba Valley region of São Paulo State. The experimental design allowed simulating different wheat crop growth conditions in the field in terms of the interactions among irrigation, cultivar and nitrogen factors. Results showed no significant interaction among the three factors for the analyzed agronomic characteristics. Interaction of irrigation and nitrogen, for grain yield and biomass, was observed only in 1999. Soil fertility was improved in 2000 with a positive effect on grain yield. Irrigation had a significant impact on grain yield indicating that wheat crop needs water supply for a profitable production in the Paraíba Valley region. Water balance is recommended for efficient irrigation.

The objective of this paper is to provide near real time information about deforestation detection (DETER) in the entire Brazilian Amazon using MODIS high temporal resolution images. It is part of the operational deforestation monitoring project to estimate the annual deforestation rate in the Brazilian Amazon (PRODES). A rapid deforestation detection method was designed to support land use policies in this region. In order to evaluate the proposed method a test site was selected covering a Landsat ETM+ scene (227/68) located in Mato Grosso State. For this purpose a multitemporal series of MODIS surface reflectance images (MOD09) and the corresponding ETM+ images from June to October 2002 were analyzed. It was found that small deforested areas (lower than 15 ha) were detected by MODIS images with lower accuracy when compared with ETM+ images. As the deforested areas increase MODIS and ETM+ results tend to converge. This procedure showed to be adequate to operationally detect and monitor deforested areas and has been used since 2004 as part of a government plan to control the Amazon deforestation.

Brazil has a wide-ranging network of rivers flowing northeast, east, north or southward. The water running off these basins may vary a great deal with climate and spatial distribution of rainfall rates. This paper analyzes the Hydrological Response (HR) of the eight major Brazilian river basins and sub-basins for a period matching 30 years of data, from 1970 to 2000. HR refers to river flow normalized by rainfall over the basin. The atmospheric forcing strongly modulates the HR at synoptic scales. At local scales, geology and land use also play an important role. The average spatial HR reached values as high as 0.7 in the west of Brazilian Amazon. We estimated “average” to “high” values in central and western Amazon (0.3-0.5) and “average” in the center-south and southeast (around 0.3). We found HR in the northeast semi-arid of Brazil classified as “very low” (close to 0.1). Brazil has climates changing from humid and rainy to semi-arid regions. Besides analyzing the regional distribution of the HR across the country, we explored the effects of the interanual variability associated with ENSO and La Niña. We used the normal climate average over thirty years as the standard for comparing the differences associated with the two anomalies. We noticed that the subbasins of the southern regions showed positive variations in water production while the Brazilian Amazon basin showed no response. Also, the areas of lower HR in the northeast Brazil were further reduced.

This study intends to evaluate the spatial analysis of the rice irrigation areas in the Medium Paraíba do Sul Valley for the period comprised between 1988 and 2003. Rice irrigation is a historical activity in Paraiba Valley being responsible for 51% of the water supply in this region. Supervised Classification was made for the multitemporal interpretation of remote sensing data (Landsat TM) using the software SPRING, ver 3.0. The analysis encompassed four regions (Guaratinguetá, Tremembé, Pindamonhagaba e Lorena-Canas), which represent 82% of the total irrigated area in the Paraiba Valley. The results show a significant decrease in irrigation area in Lorena-Canas (32.4%) and Pindamonhangaba (22.7%) and a smaller one in Tremebé region (6.4%). In contrast, Guaratinguetá region has presented an increase in irrigation area (14.2%). For the four regions analyzed, a reduction of 11.8% in irrigated area has been observed. Unlike other regions of São Paulo State, the irrigation activity in the Paraíba Valley is decreasing notably due to rapid urbanization and mineral extraction near, or on alluvial plan, contributing to the reduction of irrigated rice cultivation and elimination of wetlands ecosystems.

Climate assessment and trend analysis in air temperature and precipitation time series in Taubaté (SP)
Folhes, Marcelo Theophilo
INPE
Fisch, Gilberto
The main objectives of this paper are to present the temporal climatic characteristics of precipitation and air temperature in Taubaté (SP), in addition to the characterization of the rainy season. The time trend of the climatic elements were studied using the non parametric seasonal Mann-Kendall test. Statistically, no significant average changes in precipitation were detected although a relatively large natural year-to-year variability there exits. A short-term increasing trend from 1983 to 2005 have been observed in November precipitation, a decreasing trend in the amount of the April precipitation and a decreasing trend in the number of dry days per year. This study suggests that the onset of the Taubaté's rainy season occurs in mid-September and the end is in April.

The spatial and temporal variability of sea surface temperature (SST) for the Cuban shelf waters was obtained, and the relationship of these with lobster catches in the period from January/1997-December/2004 was analyzed. The data from this environmental variable sensor were obtained from Advanced Very High Resolution Radiometer (AVHRR). The periodicity of the images and data capture by fishing was monthly. Ocean waters and shelf have a seasonal pattern to the SST, reaching the highest in August (29.5 ° C) and the lowest in February (26 ° C). The extreme values recorded were recorded in August 1998 with anomalies of 1.9 ° C and -0.9 ° C in February 2001. During the winter period (Nov-Mar) it was possible to find a general pattern of water circulation in the area by observing the images; during the summer (May-October) this is not observed. Low correlation between SST anomalies and the catch of lobsters by fishing was observed. The best correlation coefficients (0.48) were found to the west of the island, with four years of time lag.

SAR data for the analysis of forest features: current Brazilian experiences
dos Santos, João Roberto

Gama, Fábio Furlan

Gonçalves, Fábio Guimarães

This article presents some applications of airborne polarimetric and/or interferometric microwave data to improve the knowledge of forest structures. Three airborne SAR (Synthetic Aperture Radar) experiments were done in the Amazon tropical forest: (a) to study the spatial distribution of very large trees (VLTs) in the primary forest using local maximum filtering and a series of Markov processes; (b) to model the estimation of biomass variations in primary and secondary forests; (c) to analyze the retrieval timber volume over selective logging areas. Another experiment (d) was to investigate the relation among SAR data and the volumetric configuration in stands of Eucalyptus sp done by an airborne SAR imaging mission in SE-Brazil. To perform the objectives (b), (c) and (d) we carry out regression techniques, using variables got from multipolarimetric and/or interferometric SAR attributes and biophysical parameters from the forest cover. All data from the experiments were calibrated radiometrically to extract information during digital processing, besides an exhaustive field survey which was done simultaneously to SAR imaging, to know the physiognomy/structure of forest typology and to support the models produced for each case. The results of this series of experiments show advances at the techniques to treat SAR data, focusing on models of stand architecture and forest stock density. This will be helpful to increase the regional inventory and surveying procedures of forest conversion in the Brazilian territory in the near future.

The objective of this work was to monitor and estimate soybean grain yield based on an agronomical model coupled to a Geographic Information System (GIS) using meteorological data generated by the Eta mesoscale weather forecast model. The agronomic model produced bi-weekly penalizing indices maps and soybean grain yield estimates for the States of Mato Grosso do Sul, Paraná and São Paulo, Brazil, during crop year 2004/05. Result showed that meteorological data from the Eta model, incorporated in an agronomic model, allowed monitoring, in time and space, the soybean crop. In addition, the meteorological data from Eta model are provided in almost real time allowing a quantitative and quick evaluation of weather conditions for soybean production.

The objective of this paper was to model bark volume and weight of Mimosa scabrella Bentham trees. To achieve this objective 440 trees were cubed by the Hohenadl’s method using 10 sections. These trees had ages ranging from 6 to 17 years, and were located in several counties inside the Curitiba (Parana) metropolitan region. The stems from 194 trees were weighed in the field. Samples of bark from these trees were collected, weighed in the field (green weight) and brought to the laboratory for drying until constant weight (dry weight); thus it was calculated the relationship dry weight/green weight of the sample and extrapolation for the whole stem. For the modeling, several mathematical models from the literature for estimating dry weight of Acacia mearnsii were selected. New models based on the forward’s method were also built. Twenty different models were adjusted using the 1/d²h to weight the arithmetic models with two entries and 1/d² for the models with single entry. The best models for each case were selected basing on the adjusted coefficient of determination (R²aj), standard error of estimate in percentage (syx %) and on the residual graphic distribution. In general, the new models built with variables most correlated with the respective independent variables were the most precise. The best fitting were obtained for bark volume and green weight, with syx% ranging from 15 to 18%, and R²aj from 0.96 to 0.98. The best equation for estimating bark volume in percentage presented R²aj = 0.47 and syx% = 17%.The best models for estimating bark dry weight presented higher syx% and lower R²aj than those obtained for green weight.

Evaluation of MODIS vegetation indices for detecting deforestation in Amazonia
Correia, Antonio Henrique

Duarte, Valdete
Vegetation indices (NDVI and EVI) obtained from MODIS products (250 m and 500m, surface reflectance) were evaluated in relation to the possibility of detecting and monitoring deforestation areas in Amazonia. A new vegetation index, the DNRG (Normalized Difference between Red and Green spectral bands), was proposed with the same objective. The radiometric quality of the multi-date MODIS products was evaluated to verify the possibility of using vegetation index to generate deforestation maps. The internal accuracy of multi-date composites were evaluated providing a value of positional error less than 1 pixel (< 250 m) and, consequently geometric corrections were not necessary. The potential of surface reflectance MODIS products was evaluated in the region of Terra do Meio (Pará State, Brazil, between latitudes 06?00’S to 08?00’S and longitudes 51?00’W to 54?00’W), using the Euclidian minimum distance supervised algorithm of classification. Global accuracies above 87% were obtained demonstrating a good potential for using these products in systems for deforestation detection in near real time.

Water composition undergoes complex spatial and temporal variations throughout the central Amazon floodplain. This study analyzed the spectral mixtures of the optically active substances (OASs) in water with spaceborne hyperspectral images. The test site was located upstream the confluence of Amazon (white water) and Tapajós (clear-water) rivers, where two Hyperion images were acquired from the Earth Observing One (EO-1) satellite. The first image was acquired on September 16, 2001, during the falling water period of the Amazon River. The second image was acquired on June 23, 2005, at the end of the high water period. The images were pre-processed to remove stripes of anomalous pixels, convert radiance-calibrated data to surface reflectance, mask land, clouds and macrophytes targets, and spectral subset the data within the range of 457-885nm. A sequential procedure with the techniques Minimum Noise Fraction (MNF), Pixel Purity Index (PPI) and n-dimensional visualization of the MNF feature space was employed to select end-members from both images. A single set of end-members was gathered to represent the following spectrally unique OASs: clear-water; dissolved organic matter; suspended sediments; and phytoplankton. The Linear Spectral Unmixing algorithm was applied to each Hyperion image in order to map the spatial distribution of these constituents, in terms of sub-pixel fractional abundances. Results showed three patterns of changes in the water quality from high to falling flood periods: decrease of suspended inorganic matter concentration in the Amazon River; increase of suspended inorganic matter and phytoplankton concentrations in varzea lakes; and increase of phytoplankton concentration in the Tapajós River.

The aim of this study was to compare the performance of image classifiers (Isoseg, Bhattacharyya, Maxver and Maxver-ICM) based on an accuracy analysis (set percentage, area determination and Kappa coefficient), using as ground truth an edited thematic map. For this, pre-processing techniques (atmospheric, geometric and radiometric corrections), contrast enhancement (IHS data fusion and principal component analysis) and classification of CCD/CBERS-1 and ETM+/Landsat-7 images were done. Amongst all classifiers tested, Isoseg and Bhattacharyya presented best performance for the studied classes and the study area. It is anticipated that these results are relevant to environmental analyses based on orbital satellite data.

An evaluation of the discrimination of water classes using continuum removal technique applied over spectral data obtained in field and multispectral images classification is presented. The study area was the Rodolfo Costa e Silva water reservoir, located in central region of Rio Grande do Sul (RS) State, in Southern region of Brazil. The methodology was based on in situ data collection of: total suspended solids, chlorophyll (a, b and c), water transparency, and bidirectional spectral reflectance. These data were collected in 21 point (samples) in May 16, 2006. The continuum removal technique was applied on the spectral data over 4 absorption bands: 400-550nm, 610-640nm, 650-680nm e 580-700nm. The continuum removal parameters analyzed for each absorption band were: depth, area and width. The multispectral images used were CBERS-2/CCD and Landsat 5/TM. The images were acquired in a date nearest to field work and with appropriate weather conditions. These images were corrected by removing atmospheric effects and then classified. According to the results obtained from the continuum removal technique, it was verified that band depth, area and width did not present a good potential to separate different water classes. Digital classification results did not show significant correlations with the limnological parameters collected in field and, therefore, could not be used to characterize spectrally different water classes or compartments. The main problem of establishing relationships between spectral reflectance and water quality parameters was due to the low variability of optical components in the water of Rodolfo Costa e Silva Reservoir. In this case the spectral analyses (considering both techniques) were not sensitive to the relative small variations observed in field data.

The necessary work for developing a scientific publication is sometimes underestimated and requires the effective participation of many players to obtain a result in good standard. Initially it depends upon the determination of the authors that decide to write the scientific article. Scientific writing is a very challenging and time consuming task, but at the same time essential for any scientist. A published scientific article is unquestionably one of the main indicators of scientific production, especially if published in a qualified scientific journal with highly qualified editorial committee and strict peer review procedure. By looking at evaluation criteria for scientific production of the several Thematic Scientific Committees of the Brazilian Council for Scientific and Technological Development (CNPq) it becomes clear publications in scientific journals that has certified quality is the most important item in the evaluation of a scientist production.

Conservation challenge at the agricultural frontier: deforestation, fire, and land use dynamics in Mato Grosso

Achieving conservation objectives within the rapidly changing agricultural frontier in Mato Grosso State requires tradeoffs between production and preservation. We provide a description of deforestation, fire, and land use dynamics during 2000-2005 to consider a range of strategies for conservation planning. Long-term conservation of Cerrado, transition forest, and Amazon biomes in the state can benefit from direct consideration of landscape structure, duration of post-clearing land use, and the mosaic of land uses surrounding potential conservation corridors or reserve areas. Although the creation of new protected areas may not be feasible, since few large, uninterrupted forest areas exist within the state, some conservation objectives can be met through greater coordination of the legal reserve system among property owners. We present three examples of landscape-level prioritization based on existing Forest Code regulations stipulating 80% forest reserves on private property. Through a state mediated system, property owners could augment existing reserve areas on their property through purchase of lands in: 1) buffers surrounding existing conservation units and indigenous reserves; 2) small watersheds with little or no deforestation; 3) forest patches with high connectivity within specified mosaics of different land uses. Any final approach for property-level coordination will depend on the specific conservation goals (e.g., river corridors, bird habitat, or plant biodiversity), but we provide a framework for developing and implementing a conservation plan at the agricultural frontier. Tradeoffs in both conservation value and productive use are required to achieve coordinated conservation at scale.

Spatial and temporal characterization of some water quality physical parameters and their relationships with land-use in Água Fria watershed (Palmas – TO, Brazil)
da Silva, Alexandre Marco
UNESP
Schulz, Harry Edmar
USP
Due to a high population growth that has been occurring in Palmas and due to land use changes that are caused by this population growth and development, the goal of this paper was to study the behavior of four physical parameters of water quality of the Água Fria watershed. The parameters were turbidity, total suspended solids, settleable solids and total dissolved solids. Eight gauging stations were established and the water samples were monthly collected from February/1998 to February/1999. The water bodies of the watershed were generally in good condition concerning these four parameters. However, there were some cases of seasonal irregularity of some parameters, as well as no correlation among some of studied parameters. This might be an indicator of some impacts like accelerated erosion due to a misuse of the lands and misuse of local water resources.

This paper describes a work done in the Itaim watershed at Taubaté, SP, and had the objective of estimating the surface runoff based on the Curve-Number (CN) method in area with vegetation cover of grassland (Brachiaria Decumbens), that prevails in this watershed. The surface runoff was estimated using three different methods: 1st) values of accumulated Infiltration (IAc) obtained in the field were used, considered as the Potential Infiltration (S), which varied from 15.37 mm to 51.88 mm with an average value of 23.46 mm. With those measured infiltration rates and using the maximum precipitation values for Taubaté, SP, with duration time of 3 hours: P = 54.4; 70.3; 80.8; 86.7; 90.9; 94.1 and 103.9 mm, respectively, for the return times, Tr = 2, 5, 10, 15, 25, 50 and 100 years, the following values of surface runoff were generated: 34.83; 49.33; 59.14; 64.71; 68.69; 71.73 and 81.10 mm, respectively; In the 2nd method it was considered that the prevailing vegetation cover of the watershed was Dirty Pasture (Pasture with regrowth of natural vegetation) and therefore, a value of CN = 75 was used and generated a potential infiltration, S = 84,7 mm and resulted in surface runoff values that varied from 11 to 44 mm; In the 3rd method, the value of CN was considered equal to 66.57. This value was calculated weighting the contribution of all land use cover classes of the watershed, and as a result a higher value of potential infiltration, S = 127 mm, was obtained. Consequently, the surface runoff values were 5.33; 11.64; 16.72; 19.83; 22.16; 23.98 and 29.83 mm, respectively. Therefore, the comparison with the results obtained by the two Curve-Number methods (conventional and weighted) allowed to be concluded that the Curve-Number method applied in a conventional way underestimated the surface runoff in the studied area. However, results indicate that it is possible to use this method for surface runoff estimates as long as adjustments based on potential Infiltration obtained in field be are available for local situations.

This paper presents results related to the estimation of the phreatic aquifer recharge of the Una watershed in Taubaté, SP. The goal of this study was to develop public policies for the sustainable use of superficial and phreatic water at the Department of Agrarian Sciences of the University of Taubaté. The main results of this study are: determination of the soil physical indices, characterization of the textural profile, construction of piezometers, monitoring of the watertable, determination of the hydric climatological balance, and physic-chemical and bacteriological analyses of phreatic water. The geotechnical characterization showed that the soil have high total porosity (about 53%), and natural moisture of about 30%. Regarding the results of soil particle size measurements, it was observed that the deeper the soil the more uniform is the sediments texture distribution, varying from fine loamy, to coarse sandy. It is established a consistent relation between hydric balance and porosity, saturation and piezometric measurement in a daily historical series during one year. Methods and results allowed to calculate the phreatic aquifer discharge of several springs, that varied from 14.5 mm/day in the rainy period to 1.9 mm/day in other periods. The existence of faecal coliforms in phreatic aquifer, in variable amounts, showed that there are bacterias in the water infiltrated from septic cesspools or from the nearby Itaim River, contaminated by domestic sewage.

The goal of this present work was to evaluate the net precipitation in a fragment of the Mata Atlântica biome compound of semideciduous seasonal forest in different regeneration stages in Viçosa, MG, from November of 2005 to October of 2006. It was demarcated four experimental parcels, which three of them were allocated into an initial regeneration area and one into an advanced regeneration area. Gross precipitation, net precipitation and steamflow were measured in 24 storm events, constituted of one or more storm events. The mean precipitation during the studied period was 997 mm. The net precipitation on higher advanced regeneration area that has a basal area of 3.28 m², was 813.90 mm which corresponded to 81.63% of gross precipitation. The initial regeneration area, that has a basal area of 1.22 m², was 792.46 mm which corresponded to 79.43% of gross precipitation. The canopy interception was 18.37% e 20.57%, to advanced regeneration area and initial regeneration areas, respectively. The results were statistically evaluated by t-test and f-test, and showed no significant difference on 5% of probability.

Retrospective and perspective of Ambiente e Água after one year of publication
Batista, Getulio Teixeira
Instituto de Pesquisas Ambientais em Bacias Hidrográ¡ficas (IPABHi) http://www.agro.unitau.br/lageo
After the completion of one year of publication of Ambiente e Água - An Interdisciplinary Journal of Applied Science, the following remarks can be made: three issues were published, totaling 18 articles that involved 68 authors; in addition to three editorials. The articles have come from 24 different institutions from Brazil and abroad. Some of those authors published more than one article. Most of the articles were in Portuguese (60%), others in English (34%) and in Spanish (6%). Both environmental and water resource themes appeared equally important as the main topic in nine articles each. Five articles covered both themes, simultaneously. The articles involved local studies (hydrogeology, aquifer recharge) as well as modeling large geographic areas (eight articles) that included the whole Brazilian territory (hydrology modeling), part of the Caribbean region (sea surface temperature and lobster catching), Amazonian Region with four articles (modeling water quality and deforestation), North-Central region of Brazil (conservation areas, burning and deforestation), and the Brazilian Southhern region (soybean yield and climatic modeling and forest modeling). Two articles focused on watersheds (physiographic parameters and modeling). One of the articles dealt with permanent preservation areas (PPA) mapping of a municipal district. Another article developed methodology for image analysis that can be used for environmental or water studies.

The accumulation of metallic salts in the environment resulted from the explotation, mineralogy, industrial, and agro-industrial activities and urban residues affect the dynamic balance of ecosystems, generating environmental and economic problems. The aim of this study was to evaluate the interaction of Chromobacterium violaceum with four metallic salts: aluminum sulphate, copper sulphate, manganese sulphate and zinc sulphate at concentration of 100mg/L or the absence of them, as well as a possible 2nd order interaction effect, using a complete 24 factorial design. The 16 experimental tests were carried out in microplate culture. Suspension of microorganism was prepared in Nutrient Broth and added to the orifices. After incubation at 37ºC during 24 hours, the absorbance was carried out using a 410nm in Versamax reader. The results showed remarkable bacterial adaptability. Student t test analysis showed that manganese was the only metal that did not have significant effect on the population growth of C. violaceum while zinc was the most influent. Positive interactions involving zinc was observed, interaction between aluminum and copper was not relevant.

Final disposal of solid waste is still a cause for serious impacts on the environment. In sanitary landfills, waste undergoes physical, chemical, and biological decomposition, generating biogas and leachate. Leachate is a highly toxic liquid with a very high pollution potential. The purpose of this work is to evaluate toxicity of in natura leachate samples collected from Limeira Sanitary Landfill, in Limeira, SP. The ecotoxicological evaluation comprised acute toxicity assays using as test organisms Daphnia Similis, seeds of Eruca sativa (arugula), and Allium cepa roots (onion). Analyses of color, pH, turbidity, conductivity, hardness, nitrogen, total organic carbon (TOC), adsorbable organic halogen (AOX), and metals were also carried out. The main results for Eruca sativa (arugula) and Allium cepa (onion) indicated that the diluted leachate 50% presented similar toxicity to the phenol solution of 1000 mg.L-1 for arugula and 2000 mg.L-1 for onion. With the solution of Cr+6 concentrations of 3000 mg.L-1 for arugula and 2000 mg.L-1 for onion were found. For analyses with Daphnia Similis the EC50 was 9.3% on average. This way it was possible to observe that biological tests are necessary to evaluate the pollution in the effluents or water bodies. These tests serve to determine the toxic potential of a chemical agent or complex mixture.

This study presents the application of the distributed hydrological model based on GIS – AÇUMOD to estimate the water discharges and potentialities of Pirapama river sub-basins, to be used by the Pirapama River Basin Committee (COBH-Pirapama). The model application included several steps, such as: precipitation data selection, basin discretization into cells, and model parameter calibration using try-and-error technique. The model was calibrated and validated with monthly precipitation data for the period 1987–2001. It was noted that the following parameters were the most important ones during the calibration process: infiltration function, soil minimum water capacity to generate runoff, and soil mean water storage capacity, which directly affect the computed runoff volume. The difference between observed and computed runoff during the calibration and validation processes were respectively -12.65% and 18.87%. The results of the simulated discharges by AÇUMOD, compared to observed ones, showed that the model satisfactorily represents the water basin behavior and, therefore, it can be considered a promising tool for rain-runoff simulation, permanence curve estimation, and discharge regionalization or prediction for Pirapama river basin as well as to other basins in the northeastern Brazil costal area.

This work was carried out at the Núcleo Santa Virginia (State Park of Serra do Mar), São Paulo, Brazil (45º 30' W and 23º 17' S) and has the goals of evaluating the response of the palm community in two landslide areas that occurred in the summer of 1996 due to an atmospheric event (Convergence Zone of South Atlantic). One of them is located in preserved forest area and the other in a secondary vegetation area nearby. In order to evaluate the palm community distribution, 100m2 circular plots were allocated in the edges of the scars of the landslides and in the interior of the adjacent vegetation for three altitudes (bottom, middle and top). The palms were classified in three ontogenetic stages (seedlings, juveniles and adults) which represent five species in preserved area (canopy species: Attalea dubia and Euterpe edulis, understorey species: Geonoma gamiova, G. pohliana and G. schottiana) and four species in secondary area (the same species, except G. pohliana). The disturbance caused perturbation in the palm community. The juveniles of species E. edulis and G. schottiana were stimulated by the increase in luminosity provoked by landslides while G. gamiova decreased drastically in these conditions for all developmental stages. The regeneration pattern observed indicates that species from different forest strata can respond in different ways to this type of environmental disturbance.

Actual and future climatological budget for Taubaté, SP, Brazil
Horikoshi, Andréa Sanae

Fisch, Gilberto
The goal of this study was to determine the actual water budget for Taubaté, SP and investigate the future water availability. The Thornthwaite-Mather (1955) method was used for the climatological water budget combined with observed and simulated data of air temperature and precipitation. The future scenarios indicate an increase of temperature (ranging from + 0.5 °C to + 2.7 °C) and precipitation (ranging from 80 to 150mm). These results will provoke an increase of the water deficit (ranging from 50 to 80mm) and a decrease of the surplus of water (around 200mm). The increase of the precipitation will not be sufficient to compensate for the increase of the water demands from evapotranspiration

This paper had the objective of developing a methodology to support the management of water resources, based on hydro geological cartography, tested for the hydro geologic conditions of a watershed located at Central Brazil. Results show two major products: a hydro geologic, and a potential infiltration and recharge maps of the high course of the Rio da Palma watershed. This paper is presented in six parts. The first one discusses the map’s elements, essential thematic maps and appropriate scales. The second part proposes the graphic criteria for the integrated representation of the major parameters of overlaying aquifers. The third part demonstrates the importance of the data basis for the hydro geologic cartography, i.e., the contribution of each theme such as soil, geology, slope, climate and land use, when appropriately integrated. The fourth part discusses the selection and the integration of the main information layers for the Rio da Palma watershed using a Geographic Information System (GIS). On the fifth part, the result of the integration of the porous domain with the fractured domain aquifer information layers is shown and, finally, the potential infiltration and recharge map of the studied area, elaborated from the integration of overlapping of the data basis information layers is presented and discussed. In general, in the studied area, regions with high infiltration potential prevail where human interference is still moderate. Large portions of low infiltration potential are either associated with high slopes, with shallow soils (Cambissolos) or else with urban constructions.

Universidade de Taubaté http://www.agro.unitau.br/lageo
The objective of this work was to outline and to characterize the sub-basins of the Alto Rio Jamanxim hydrographic basin and to code them using the concept of “otto-basins”, as well as to quantify the deforestation area and the increase in roads extension in its drainage area from 1999 to 2005. The work was based on data of river’s and road’s network, digital elevation model (DEM), and four TM/Landsat-5 images from 1999 and 2005. The outline of the boundaries and the hydrologic parameters of the Basin were based on a 1:250,000 DEM. Results have shown that nine sub-basins have been outlined in the study area, coded up to level 5 (otto-basin code system) and identifiers varied from 44291 to 44299. Deforestation by human activities totaled 635km2 (11% of the Basin) up to 1999 and to 1,257km2 up to 2005, therefore, an increase of 622km2 or 98% between these two dates. Regarding the road network, a total extension of 1,685km was mapped up to 1999 and 3,638km up to July 2005 what corresponds to an increase of 116% in road construction inside the basin boundaries in six years.

Scientific Journal Indexing
Batista, Getulio Teixeira
Instituto de Pesquisas Ambientais em Bacias Hidrográ¡ficas (IPABHi) http://www.agro.unitau.br/lageo
It is quite impressive the visibility of online publishing compared to offline. Lawrence (2001) computed the percentage increase across 1,494 venues containing at least five offline and five online articles. Results shown an average of 336% more citations to online articles compared to offline articles published in the same venue. If articles published in the same venue are of similar quality, then they concluded that online articles are more highly cited because of their easier access. Thomson Scientific, traditionally concerned with printed journals, announced on November 28, 2005, the launch of Web Citation Index™, the multidisciplinary citation index of scholarly content from institutional and subject-based repositories (http://scientific.thomson. com/press/2005/8298416/). The Web Citation Index from the abstracting and indexing (A&I) connects together pre-print articles, institutional repositories and open access (OA) journals (Chillingworth, 2005). Basically all research funds are government granted funds, tax payer’s supported and therefore, results should be made freely available to the community. Free online availability facilitates access to research findings, maximizes interaction among research groups, and optimizes efforts and research funds efficiency. Therefore, Ambi-Água is committed to provide free access to its articles. An important aspect of Ambi-Água is the publication and management system of this journal. It uses the Electronic System for Journal Publishing (SEER - http://www.ibict.br/secao.php?cat=SEER). This system was translated and customized by the Brazilian Institute for Science and Technology Information (IBICT) based on the software developed by the Public Knowledge Project (Open Journal Systems) of the British Columbia University (http://pkp.sfu.ca/ojs/). The big advantage of using this system is that it is compatible with the OAI-PMH protocol for metadata harvesting what greatly promotes published articles visibility. Currently, there are 687 conformably registered repositories in OAI. The Public Knowledge Project – Open Archives Harvester2. lists Ambi-Água: http://pkp.sfu.ca/harvester2/demo/index.php/browse/ index/677. At the OAI base the URL of Ambi-Água is http://www.agro.unitau.br/ seer/index.php/ambi-agua/oai?verb=Identify. Therefore, all Service Providers are automatically capable of harvesting metadata from Ambi-Água articles.

In this study, two hydrological models to estimate soil losses and sediment yield due to sheet and channel erosion, at the basin outlet, are applied to Guaraíra River Experimental Basin, located in Paraíba State, northeastern Brazil. The soil erosion models are (a) the classical Universal Soil Loss Equation (USLE), which is used to simulate annual and monthly soil losses; and (b) Kineros model, which is used to simulate the sediment yield within the basin. Kineros model is a physically-based distributed model that uses a cascade of planes and channels to represent the basin and to describe the processes of interception, infiltration, surface runoff and erosion within the basin. The USLE is computed using land use, soil erodibility, topographic digital maps, as well as observed rainfall data. It was found that Guaraíra river experimental basin has a low potential for soil losses; however, specific areas which are susceptible to the erosion process in the basin could be detected by the modeling techniques coupled to a GIS (Geographic Information System).

This paper presents an environmental analysis of the fragility of Pindaíba Creek Hydrographic Basin using the analysis of natural and anthropic components interactions in the study area. The main objective of this research was to identify and map the environmental fragility of this basin. The specific objectives consisted in the physical characterization of land use and land cover. To accomplish this research, several field campaigns were conducted throughout the basin. The cartographic base was compiled using the Taboca and Pau Furado charts at 1:25.000 scale that were digitized using the software Cartalinx. The thematic maps of geology, geomorphology, and land use were compiled using the software Arcview 3.2. The fragility map was also derived based on the software Arcview 3.2 using the tool Geoprocessing Wizard. The methodology developed by Ross (1990, 1994) was used for the evaluation of the landscape fragility. This methodology attributes values to environment variables according to their potentialities. Results allowed the identification of major natural and anthropic actions in the study area represented in a map of fragility potential. These results indicate that land use has to be changed in order to adjust to the landscape morphology, considering not only natural resources, but also the needs of the people who live in the study area.

Among the indirect methods to evaluate the volumetric soil water content (?v), the Time Domain Reflectometry (TDR) technique is receiving growing attention. As any technique, it presents advantages and disadvantages: the most serious disadvantage is the calibration necessity. At the present study, values of apparent dielectric constant (Ka) and volumetric water content (?v) for a Red Latosol were obtained in a laboratory experiment, using seventeen probes of TDR, from which two were original and fifteen were manufactured by the staff. This study aimed: a) to calibrate the seventeen probes, in laboratory conditions, comparing six regression models for each probe; b) to verify the viability to use the manufactured probes. It was found out that the best regression model was the cubic polynomial model and that the manufactured probes presented performances comparable to the original ones.

Floods in urban areas are responsible for impacts that go from puddles formation to environmental and social disasters. Looking for alternatives to minimize the effects of floods in urban areas, some methodologies have been studied and applied, such as the use of detention basin in high consolidated urban areas. This study analyses the efficiency on flood control of two detention basins, a dry and a wet one. The study approaches both quantitative and qualitative aspects related to runoff from an urban area of Brasilia city, federal district of Brazil. The affluent caught by the detention basins is related to a conventional urban drainage system with a 4.75km2 (dry basin) and 6.12km2 (wet basin) contribution area. The results showed that the basins can reduce the peak income flow significantly (averaged 62.6% and 74% peak flow reduction, for dry and wet basin, respectively) and has positive impact over pollution control, with an average reduction of 1 to 3% for BOD and up to 41 to 74% for Suspended Solids.

This paper presents a methodological approach to characterize the infiltrations conditions of a portion of Paraiba do Sul river basin (7,600 km2) using Geographic Information Systems tools. To each landscape feature (rock, structure, relief, soil, and land-use) and to the spatial distribution of precipitation, an infiltration potential scale factor that ranges from higher influence (5) to lower influence (1) was applied considering its geographical position. The results showed that higher infiltration capacity areas are located in Serra da Bocaina associated to Serra do Mar relief in the Northeast region and Southeast region as well associated to gentle hills and sandstones along the Paraíba do Sul river. The creation of an Infiltration Map may contribute to the development of long-term territorial plans and water resource management plans in order to support future implementation of non-structural and structural measures at both regional and local scales.

The study of hydrographic basins as territorial units integrating the management of hydric resources is essential to guarantee sustainable use of natural resources in these basins. The establishment of the Paraíba do Sul hydrographic basins committee, in 1994, determined the need for management planning and action integration in the Paraíba do Sul basin which incorporates a variety of industries and intense land use. The Batedor river, in the municipality of Cruzeiro, SP, flows into the Passa Vinte which is an affluent of Paraíba do Sul river. Its mouth is located at 22°31’0.63”S and 45°01’2.07”W. Its farthest water contributing source lies about 8.5 km, near the Itaguaré peak 2,308 m high, in the Mantiqueira Mountain on the border of São Paulo and Minas Gerais States. To characterize land use in the Batedor hydrographic basin, Landsat imagery and topographic charts were analyzed based on remote sensing and geoprocessing techniques. This paper describes the study of impacts related to land and water resources use in the Batedor river basin and the generation of educational environmental material. Results have shown that this basin has good water supply, has no flooding risk and has several springs running down the Mantiqueira Moutain slopes that form young creeks with few meanders. Irregular human occupation for housing and subsistence agriculture, mainly banana plantations can be seen in deep slopes and riparian areas, as well as degraded pastures that indicate inappropriate land use and no conformance to pertinent legislation. The decrease in forest vegetation cover can cause severe erosion with significant soil loss and sediment deposition in the river, thus reducing water quality and quantity during the dry season. This basin is currently responsible for 70% of the Cruzeiro, SP water supply.

The use of appropriate cartography database is extremely important to support projects of planning and land management. However, the absence of maps, or the amount of obsolete maps, has been leading to the adoption of alternative methodologies aiming to faster and less onerous solutions for the development of cartography databases, without compromising quality. Regarding this problem, the present paper reports on the viability of constructing a cartographic database designed for applications in hydrology, more specifically, as a base for a Decision Support System for Urban Basin Management - DSSURM. The methodology combines techniques of manual terrain features extraction, as well as automatic techniques of photogrammetry. Digital orthophotos and contour maps were generated. The coarser 5 meters interval was used for the mountainous regions and forest, and the finer 1 meter interval for other regions, floodplains were prioritized for mapping flooding areas. The final analyses show the viability of the methodology as well as the high quality of the cartographic products.

This paper discusses the use of a Landsat Thematic Mapper (TM) and JERS-1 Synthetic Aperture Radar (SAR) time-series for mapping and monitoring land cover types in a test site in the region of Corumbiara, Rondônia State, western Brazilian Amazônia. In order to support JERS-1 data analysis, land cover maps were obtained by digital classification of Landsat TM images acquired from 1993 to 1997 period, following a procedure based on image segmentation, unsupervised classification, and post-classification image edition. The comparison of these products with JERS-1 temporal images shows that clear-cut areas are well-identified presenting a low backscattering response as expected. On the other hand, areas that have been cleared and even burned but with remaining forest material left on the ground present high backscattering response. Considering these observations and user interpretation expertise, temporal SAR images present an effective source of information for mapping and monitoring deforestation, especially in areas covered by clouds with restricted use of optical data.

Geographical impact of scientific journals
Batista, Getulio Teixeira
Instituto de Pesquisas Ambientais em Bacias Hidrográ¡ficas (IPABHi) http://www.agro.unitau.br/lageo
One important quality measure of a scientific journal is its scope, not just the scientific coverage, but also the geographical impact. In fact, the primary classification system, used to evaluate and grade scientific journals' quality in Brazil, known as Qualis CAPES, when classifying a journal attributes a quality grade A, B or C, and also adds an indication of the journal´s geographical impact: Local, National or International. This classification system is used by several other institutions, especially by research funding agencies, for instance, CNPq, whose thematic committees use Qualis CAPES classification to quantify the researchers' and Research Groups' productivity. This article discusses several possibilities for geographical impact evaluation and presents the mechanism used by Ambiente e Água – An Interdisciplinary Journal of Applied Science (Ambi-Água) to monitor the extent of its spatial impact.

Hydrographic basins in urban areas frequently undergo drastic landscape changes. This work analyzed the landscape transformation of Vidoca Stream Watershed in the period from 1500 to 2003. Based on Remote Sensing and GIS techniques it was found that: a) Between 1500 and 1953 natural vegetation classes which included Alluvial Semi-decidual Seasonal Forest, Mountainous Semi-decidual Seasonal Forest and Open Arboreal Savannah changed to anthropic fields and grasslands; b) From 1954 to 1985, just before the massive urban occupation of the area, there was a short period of regeneration of the Alluvial Semi-decidual Seasonal Forest above the Carvalho Pinto Highway; later on, the grasslands changed to anthropic fields; c) From 1986 to 1997, a fast urbanization process occurred and resulted in the replacement of the grassland and anthropic fields by urban constructions; d) From 1998 to 2003, with the consolidation of the urbanization process, the urban occupation reached the boundaries of the plateau and the lowlands of the watershed, resulting in soil impermeabilization. The results of this research indicated that the urbanization process was not controlled in spite of restricted legislation and environmental degradation occurred in this studied watershed along of the study period.

This work presents the determination of saturated areas in the Pequeno River watershed (104 km2), located in the São José dos Pinhais District, Metropolitan Region of Curitiba, Paraná State, Brazil. We employed the hydrological model TOPMODEL which assumes that the water dynamics are influenced by soil and hillslope characteristics of the entire watershed. It calculates the runoff and the spatial distribution (saturated and unsaturated areas) of the soil humidity in the system throughout the considered time period. The maps of the saturated areas were analyzed taking into account the land use and riparian vegetation (permanent preservation). The computations showed a good adherence between calculated and observed runoff (R²=0.75), thus confirming the model efficiency in regions of humid climate and smooth topography. The simulation results reveal a potential application for environmental planning because they allow the discussion and further orientation for human interventions in the environment based on the understanding of the natural processes.

The present work was carried out in order to study the performance of the tifton 85 (Cynodon spp) grass cultivated in wetlands (SACs) and submitted to different organic load application rates (TCOs) of milk processing wastewater (ARL), in the climatic conditions of Viçosa - MG. The experimental structure was constituted by five SACs with horizontal subsuperficial flow, using tanks of 0.40 x 0.75 x 3.00 m (depth, width and length) filled with 0.33 m depth of fine stones. The ARL was applied in average flow of 60 L.day-1, hydraulic time residence of 4.8 days and TCOs of 66, 130, 190, 320 and 570 kg.ha-1.day-1 of DBO. The tifton 85 grass adapted well to SACs, presenting good rooting, high yield and capacity of nutrients (N, P and K) and sodium removal of the ARL, whose values were, respectively, between 216 - 544, 24 - 61, 115 - 204 and 4.3 – 10.9 kg.ha-1.

The objective of the present study was to evaluate the water balance in the Cubatão-Sul river catchment (403.83 km2), Santa Catarina State, Brazil, which is very important for irrigated horticulture and drinking-water supply to the Great Florianópolis Region. The daily data obtained from the Poço Fundo hydrometeorological station and São José Meteorological station during the period between 1977 and 1994 were used for the analysis. A lumped and storage model HYCYMODEL was used for both water balance and evapotranspiration analyses and five additional methods were used for the evapotranspiration analysis. The results from the HYCYMODEL showed that the total discharge and the evapotranspiration in the catchment are approximately 62% and 44% of the annual rainfall (1563 mm), respectively. The total discharge consists on the direct runoff of 26% and the base flow of 74%. The actual evapotranspiration estimated with the water budget method was practically equal to that obtained with the HYCYMODEL. And the values of the ratio of the annual actual evapotranspiration to the annual potential evapotranspiration are 0.39, 0.58, 0.65 and 0.69 for Hamon method, modified Penman method, Blaney and Criddle method and Thornthwaite method, respectively. The increasing rate of the discharge over rainfall is larger than that of the evapotranspiration. When the annual rainfall is more than 930 mm, the discharge is always larger than the evapotranspiration.

The Brazilian production of coconut has not been sufficient to attend the internal market demand which has resulted in great importations of dry and semi industrialized coconut (IBGE, 2006). The northeast of Brazil has the greatest coconut production and is, at the same time, characterized for its high evapotranspiration demand and the lowest precipitation, therefore, it is necessary to optimize the irrigation water used. During the development phase of the coconut tree, most of the root system concentrates around 1m of radius, and in the adult phase, in larger part, to a radius up to 2m. The traditional procedure of calculation of the water volume to be applied through irrigation, normally considers the area given by the crop planting spacing and a canopy cover coefficient. This results in great volumes of water applied unnecessarily. To save water, this study investigates the calculation of the volume of irrigation water considering the areas where larger concentration of the root system occurs. For the first year of development of the coconut tree, four areas of irrigation delimited by rings of zinc with diameters of 0.7 m, 0.8, 0.9 and 1.0 m were used to irrigate the portion with the larger concentration of the root system, and two conditions of soil covering (covered and bare soil), plus a control (4 x 2 + 1), resulting in nine treatments with three repetitions, totaling 27 plots. The procedure proposed in this research for the calculation of the water volume to be applied in the coconut crop, based on areas of larger concentration of the root system, promoted considerable economy of water, in relation to the procedure traditionally used. The isolation of the soil surface in order to avoid the evaporation contributed to a substantial reduction of the applied volume of water as well.

Controlled disposal of domestic effluent sewage in the ground to reduce fecal coliforms
Castro Ribas, Teresa Blandina
UNITAU
Fortes Neto, Paulo
UNITAU
The indiscriminate launching in water bodies of domestic sewage without treatment, or even treated, but without appropriate disinfection, contributes with significant amount of organisms of the called "coliform group” that can carry specific illnesses agents propagated through the water. The application of effluent in the ground, instead of direct disposal in water courses, in addition to being an alternative way for the disposal of residues and biological control of pollutants, constitutes an adequate way of nutrients supply to the soil and plants. So, this work had as objective the evaluation of the reduction of fecal coliforms, after controlled applications of 60 days treated effluent in cultivated soil, by analyzing the increase of fluorescent rhizobacterias Pseudomonas fluorescens and Bacillus spp. present in the rhizospheres of different crops. The experiment was developed in field conditions in the Experimental Farm of Department of Agrarian Sciences of the University of Taubaté, municipality of Taubaté, SP. The Experimental design consisted of random blocks, with five treatments including annual crops (Oats, Barley, Triticale - a cross between wheat and rye, Black Beans and non-cultivated soil as witness - blank reference) and four repetitions, totalizing 20 ground plots with area of 2 m x 1 m with 50 cm space among plots on a Dystrophic Red-Yellow Latossol. Results from the microbial analyses of rhizosphere and non-rhizosphere soil indicated that the rhizosphere of oats had denser rhizobacterias than the other crops. However, the greatest efficiency was found in the reduction of thermo-tolerant coliforms for both black beans and non-cultivated soil.

There are emissions of mercury to the atmosphere, soil and rivers of the Brazilian Amazon stem from many sources. Once in the atmosphere, the metal is oxidized and immediately deposited. In the water, the transformation to methylmercury takes place mostly by the action of microorganisms. The formation of methylmercury increases the dispersion and bioavailability of the element in the aquatic environment. Methylmercury can be assimilated by plankton and enters the food chain. The concentration of mercury increases further up in the trophic levels of the chain and reaches the highest values in carnivorous fishes like tucunare. Therefore, mercury emissions cause the contamination of natural resources and increase risks to the health of regular fish consumers. The objective of this work was to study the bioaccumulation of mercury in tucunares (Cichla sp.), top predators of the food chain. The fishes were collected at two locations representative of the Amazonian fluvial ecosystem, in the state of Pará, Brazil, in 1992 and 2001. One location is near a former informal gold mining area. The other is far from the mining area and is considered pristine. Average values of total mercury concentration and accumulation rates for four different collection groups were compared and discussed. Tucunares collected in 2001 presented higher mercury contents and accumulated mercury faster than tucunares collected in 1992 notwithstanding the decline of mining activities in this period. The aggravation of the mercury contamination with time not only in an area where informal gold mining was practiced but also far from this area is confirmed.

The objective of this work was to evaluate hydrological and environmental issues of Cachoeira das Pombas watershed, in Guanhães, eastern Minas Gerais State, Brazil, to support its management plan. The characterization of water springs included the definition of its types, assessment of flow persistence, conservation state, outflow values, and the hydrological and environmental conservation state of the watershed. For a detailed analysis, the watershed was studied considering each of its small watersheds. Analyzing the hydrological and environmental conservation state of the watershed, it was concluded that an integrated management of natural resources is necessary inasmuch as the flow rate showed to be irregular, with great variation between the rainy and dry seasons and several erosion and silting spots observed during the study period.

Phytoplankton density and trophic state of Canha and Pariquera-Açu rivers, Ribeira de Iguape hydrographic basin, SP, Brazil

Regarding the lack of studies about lotic eutrophication, mainly for tropical rivers, this research aimed to assess the density of phytoplanktonic community of two tropical rivers located in Ribeira do Iguape Watershed (São Paulo state, Brazil), Canha and Pariquera-Açu Rivers, based on sampling campaigns in January and April, 2007. These results were compared to the mTSI (mean Trophic State Index) values. This index was originally developed for lentic aquatic systems and its calculus depends on total phosphorous, orthophosphate and chlorophyll-a concentrations in water samples. Comparing mTSI values in all sampling stations with the phytoplankton quantitative results, it was possible to verify that mTSI may overestimate the trophic state of lotic ecosystems, since the phosphorus species that integrate its calculus contributed to an improper augmentation on mTSI, which were incompatible with the real associated biological response. Thus, for April sampling, although mTSI values were higher, in general, phytoplankton density were lower (minimum of 83 indmL-1 for Canha River and of 66 indmL-1 for Pariquera-Açu River). In this case, the high total phosphorous concentrations by themselves were not enough to promote proportional phytoplanktonic growth, which was probably limited by other factors, like water temperature, suspended solids concentration, river discharge and zooplanktonic predation. In January, on the other hand, mTSI values were lower, but total phytoplankton density was higher. For this sampling, the lower orthophosphate concentrations in water pointed phytoplankton assimilation of this nutrient.

Evaporative cooling: water for thermal comfort
Camargo, José Rui
Mechanical Engineering Department, UNITAU, University of Taubaté
Evaporative cooling is an environmentally friendly air conditioning system that operates using induced processes of heat and mass transfer, where water and air are the working fluids. It consists, specifically, in water evaporation, induced by the passage of an air flow, thus decreasing the air temperature. This paper presents three methods that can be used as reference for efficient use of evaporative cooling systems, applying it to several Brazilian cities, characterized by different climates. Initially it presents the basic operation principles of direct and indirect evaporative cooling and defines the effectiveness of the systems. Afterwards, it presents three methods that allows to determinate where the systems are more efficient. It concludes that evaporative cooling systems have a very large potential to propitiate thermal comfort and can still be used as an alternative to conventional systems in regions where the design wet bulb temperature is under 24ºC.

This paper shows the results obtained from several pump tests of two wells drilled 13.2 meters apart, in the Agrarian Sciences Department of the University of Taubaté farm, located in the Una river hydrographic basin, Taubaté municipality, State of São Paulo, Brazil. During well drilling some difficulties were encountered due to the presence of sandy grains without inter-granular cementation of the Tremembé Formation sandstones, Taubaté Group. The detailed description of the geologic profile obtained by sampling the perforated sedimentary layers shows the presence of persistent sandstone and conglomerate sequences, intercalated by layers of shale and claystone with limestone nodules. In order to determine the hydrodynamic parameters of the Tremembé aquifer, several pump tests were conducted during well perforation and the unconfined, leaky, water-table, and confined aquifer layers were sampled. Once the boreholes were completed, tests were conducted to determine maximum discharge rate, interference between wells and artificial recharge potential. In addition to establishing appropriated methodologies for the determination of aquifer hydrodynamics, this paper describes techniques for interpreting the effects of artificial recharge and interference between wells, and demonstrated the application of image well theory complemented with a new theory, the image well water-mirror.

Ambiente e Água – An Interdisciplinary Journal of Applied Science in its third year of publication
Batista, Getulio Teixeira
Instituto de Pesquisas Ambientais em Bacias Hidrográ¡ficas (IPABHi) http://www.agro.unitau.br/lageo
This April 2008, volume 3, number 1 issue of Ambiente e Água – An Interdisciplinary Journal of Applied Science is a landmark for Ambi-Água to achieving national and international recognition. This year it is expected that the primary system for scientific journal evaluation in Brazil, QUALIS CAPES (http://qualis.capes.gov.br/webqualis/) will review the quality and geographical impact of Ambi-Água inasmuch as many Lattes curricula of scientists involved in Brazilian post-graduate programs show publications in Ambi-Água in the last two years. Batista (2007a) discussed details of CAPES evaluation procedure. In addition to the quality appraisal, CAPES also indicates the regional impact of scientific journals as local, national or international. Once a journal is evaluated by CAPES and has three years of on-time publications, CNPq, the major scientific support agency in Brazil, accepts applications for funding that journal. This may significantly improve the operational facilities of a granted journal. Ambi-Água editorial board is proud to announce that since its first issue it has been circulating on-time.

The main usages of surface water near to the former Roger’s open dump were investigated by means of visits every three months. These visits were performed in: March 2006, August 2006, November 2006, February 2007, May 2007 and August 2007. The following activities were identified: fishing, crustacean and shellfish catchments, primary contact bath, discharge of sewage, disposal of solid wastes, and discharge of leachate generated by the former open dump. Furthermore, social-economical questionnaires were applied to the people living nearby. Results showed that 50.2% of interviewed people stated that uses the Sanhauá river water for fishing or crustacean or shellfish catchments; 45.8% said that use the river for primary or secondary contact bath or navigation; 93.1% of interviewed people said that their houses were not attended with sewage and so that, the final disposal site for the sewage was the Sanhauá river. Although all houses are attended by solid waste collection services, 46.6% of the interviewed people declared to know about solid wastes disposal at the Sanhauá river. According to these usages and CONAMA Resolution 357/2005 and the water salinity, the Sanhauá river would be classified into class 1 for brackish water, as opposed to its present classification: class 3. The monitoring showed that water quality standards were not in accordance to the class 1 for brackish water. Therefore, the environmental institution should adopt measures so that the water quality of Sanhauá river would be maintained or proceed to the revision for the river classification.

Water supply systems, due to their configuration, tend to be vulnerable to internal and external threats, which can potentially cause instability in water distribution. The vulnerability assessment is a tool that has been used to ensure the water supply in different failure scenarios, and can assist in seeking alternatives for supplying water in emergency situations. This work aimed mainly at determining the most important or critical segments for an adequate performance of the water supply system when there are emergency conditions such as the ones caused by natural disasters. The system’s hydraulic performance was evaluated based on simulations using EPANET 2.0. The vulnerability was determined by using an application written in Visual Basic 6.0 to customize EPANET using its Programmer's Toolkit. The system vulnerability was determined with the interruption of one segment at a time to calculate, in a dynamic way, the importance of each segment to the system, and by comparison of these results to the index of relative importance by flow rate. The results showed that using the indices Vulnerability-System and Vulnerability-Node was adequate to establish the importance of a critical segment in the performance of a network.

The Environmental Sensitivity Index Maps for Oil Spills (ESI Maps, or SAO in Portuguese) constitute an essential component and source of basic information for emergency planning, response decision support and damage evaluation in case of oil spills. This study aims at the elaboration of sensitivity maps for oil spills for the islands within the Ubatuba municipality, north coast of the State of São Paulo. The adopted methodology is based on the Technical Specifications for the production of Environmental Sensitivity Maps for oil spills (SAO maps) proposed by the Brazilian Ministry of Environment. The study involved the gathering of secondary data, followed by field work carried out in the summer and winter periods of 2007; the elaboration of the cartographic base maps and, finally, the integration of the data to a GIS (Geographic Information System). As a result it was registered and mapped the physical (geology, geomorphology, oceanography and climatology), biological (fauna, flora and coastal environments) and socioeconomic (anthropic influence, human use, artificial structures and impacts) resources of Ubatuba coastal islands. Eleven beaches have been identified, located at six islands, with distinct topographic and geomorphologic features. The beaches were classified with sensitivity index 4, because they are sheltered from actions of waves and currents. Most of the mapped environments (44.8%) were classified with sensitivity index 8, indicating high sensitivity of the islands. The oil spill impacts on coastal environments can be significantly minimized during the contingency actions when previous knowledge of the ecosystems that compose the islands environment is available, especially when it is integrated into GIS data basis, capable of displaying easy-to-use maps. The environmental sensitivity mapping is an important management instrument, especially when dealing with sensible and poorly studied areas such as the islands of Ubatuba.

Evaluation of regionalization flows models performance at Santa Bárbara River Basin, Goiás, Brazil
Fioreze, Ana Paula

Franco, Alexandre P. Barbosa
Information on river flows is essential for water resources management. Most of the Brazilian small watersheds is ungauged. Regionalization of hydrologic information is an alternative way to get this lacking information. The regionalization models, however, are a simplified representation of natural phenomena, what could lead to miscalculation. Therefore, these models should be tested before being used as a management tool. This paper evaluates the performance of the regionalization models created for the Santa Bárbara River Basin region, in Goiás. This river basin is located between 17º45’ and 18º15’ South and 49º36’ and 50º03’ West and has a catchment area of 1371,16 km2. The models estimate average streamflow, maximum streamflow, minimum streamflow, the 95% duration streamflow, the seven day, ten years, minimum streamflow and the monthly-average streamflows. The tested streamflow regionalization models proved to be good enough for average flows, but not for maximum and minimum events. The models based on homogeneous regions were superior to those that ignored that aspect. The model that uses drainage area and density to estimate the 95% duration streamflow could be used in water resources management with little error. The use of this model would better represent the water availability at Santa Bárbara River Basin than a few local measurements currently used.

The impacts of Hg2+, Cd2+ and Zn2+ on the activities of periplasmic nitrate reductase (NAP) and dehydrogenase (DHA) enzymes of three organisms isolated from soil and sediment-water interface were analysed in liquid culture studies. NAP and DHA activities were estimated from nitrite and triphenyl formazan were produced respectively after 4h incubation at 28 ± 2oC. Hg2+ completely inhibited NAP activity in Escherichia and Pseudomonas spp at all the concentrations (0.2 – 1mM) while progressive inhibitions of NAP activity were observed in Escherichia and Pseudomonas spp with increasing concentrations of Zn2+ and Cd2+. Both metals were stimulatory to NAP of Acinetobacter sp at 0.2 – 1mM. Apart from stimulation of DHA activity by Zn2+ (0.2 – 1mM) in Escherichia sp, Cd2+ (0.4 -1.0mM) in Acinetobacter sp and (1.0mM) in Pseudomonas sp, all the metals progressively inhibited DHA activities in the three organisms. In Escherichia sp, the activities of the two enzymes were negatively correlated on exposure to Zn2+ (r = -0.91) and positively correlated (r = >0.90) on exposure to Cd2+ and Hg2+. Based on IC50 values of the metals for the DHA and NAP enzymes, the most resistant of the three organisms were Escherichia sp and Acinetobacter sp respectively. Quantitatively, NAP with its lower IC50 values than DHA was a more sensitive toxicity measure for Hg2+ in all the organisms. The sensitivity of microbial metabolic enzymes to the toxic effects of metals varies with the type of enzyme, metal and the microorganism involved.

The Fernando de Noronha archipelago is composed by 21 islands. The biggest of them, the Fernando de Noronha island, is supplied in domestic water by two reservoirs, one rain-water collecting system and another system using sea water desalinization. In addition, this island is supplied by water from six secondary artificial ponds and some wells and springs. However, during the summer drought time, the island endures a water supply reduction that endangers the touristic activities, which are the main economical local financial source. In this concern, were evaluated the quality of the water from several sources for human supplying. Some measurements were performed “in site” and laboratory physical chemical analyses as well. It could be concluded that a further reorganization of the water supply system ought to be carried out in order to avoid future problems and risk of water supply collapse in this island.

In order to determine the occurrence of antimicrobial-resistant Enterobacteriaceae, 506 samples of drinking water, surface water, and ground water were studied in the province of Chaco, Argentina. One hundred and ninety one isolates of Enterobacteriaceae Family members were obtained. The most frequent specie was Escherichia coli and it showed the highest rate of acquired resistance, being the ?-lactams the most affected antibiotics. The findings of the present work suggest that the occurrence of antimicrobial-resistant bacteria in aquatic ecosystems of Chaco may contribute to the environmental dissemination of antibiotic resistance.

The objective of this study was to determine the dissolved inorganic carbon (DIC) and pCO2 concentrations in two third order streams in southwestern Amazonia, Brazil. From May 2004 to June 2005 water dissolved oxygen, pH, electrical conductivity, temperature were measured to stream water chemical and physical description. DIC and pCO2 measurements were made by headspace extraction and gas samples for pCO2 and DIC extractions were run on an infrared gas analyzer (IRGA, LI-COR Instruments model LI-820). Results indicate a relationship between soil type and water chemistry, where sandy soil stream presented lower pH than silty soil stream – consequently DIC and pCO2 concentrations also varied with soil type. Mean DIC concentration for sitly soil stream was 403±130 ?M month-1, while sandy soil stream DIC concentration was 170±59 ?M month-1. Free CO2 was the dominant form of DIC in both streams. Nevertheless, HCO3- contribuition to DIC was greater for the silty soil stream. DIC contentration also varied seasonally with greater values in the drier period. Absolute pCO2 values were greater for silty soil stream, mean 3067±1228 µatm month-1 and 2321±1020 µatm month-1 for sandy soil stream. Seasonality, pCO2 was higher in the dry season in both streams. Our findings have important implications on the role of soil type in water chemistry and carbon dynamics and also are used in other studies on carbon balance at the landscape level.

Geoelectrical characterization of contaminants from domiciliary solids waste decomposition
Moreira, César Augusto
UNESP
Braga, Antonio Celso de Oliveira
UNESP
This paper presents the results of the Electrical Resistivity geophysical method applied to determine the area of leaching migration originated from solids waste decomposition, disposed in ditch type landfill. When the monitoring of wells or other direct techniques of the environmental investigation is not possible, the geological characterization, supported by geophysics techniques is an alternative for the assessment and monitoring leached materials. The absence of values below 100 ?.m in the reference line at 4 m of depth and the occurrence of these values in the residues ditches and its surroundings indicate the presence of leachate. This relation is a result of the high content of total dissolved solids that characterize the studied contaminant that reduces the electric resistivity.

Instituto de Pesquisas Ambientais em Bacias Hidrográ¡ficas (IPABHi) http://www.agro.unitau.br/lageo
The publication of the seventh edition of “Revista Ambiente e Água – An Interdisciplinary Journal of Applied Science (Ambi-Água)” demonstrates the international visibility that the journal is reaching. An unprecedented number of submissions has been received for this issue and resulted in an increased number (50%) of published articles, as compared to the first two volumes that had six articles published. This issue brings nine peer reviewed articles out of which 5 are published in English. Among those two were submitted from abroad (Nigeria and Argentina) in addition to several paper co-authors from the United States. The participation in the authorship of public universities and municipal, state and federal institutions was also significant. There were 18 authors in this issue from those institutions not considering those authors from abroad. There was also a thematic coverage expansion of articles within the interdisciplinary scope of Ambi-Água. An example of this is an article in Engineering concerned with thermal comfort in urban areas; several submissions in environmental chemistry with two published articles (organic and inorganic chemistry); one article in the area of public health and antimicrobial resistance in aquatic ecosystem; other in sensibility to oil spilling charting in coastal islands; chemical contamination in fish due to the improper land use in Amazonia; and two articles in hydrological modeling in watersheds. Powered by the OAI-PMH protocol (Batista, 2007), which greatly enhances the visibility of the journal, in addition to the fact that Ambi-Água appears in several international indexing systems and its free on-line availability with open access policy, the journal is being frequently consulted. In only two months (June 15 to August 15, 2008) there were 4,556 consultations with an average of approximately 500 consultations a week. These consultations came from 616 cities, 79 countries, and five continents in that period.

Amylase production by Citrobacter sp. isolated from potato was optimized in batch culture studies under shake flask conditions. Effects and interactions of best sources and levels of carbon and nitrogen estimated by 4 x 5 and 4 x 4 factorial experimental arrangements were significant (P < 0.01) on amylase production. Optimal alpha-amylase yield was obtained in a medium containing sorghum flour (2.0 % w/v) and a mixture of (NH4)2SO4 + soybean meal (1.5% w/v) with an initial medium pH of 8.0. Under optimum conditions, amylase yield was maximal (0.499 U/ml) after 60h incubation at room temperature (28oC ± 2oC). Characterization studies showed that the enzyme had maximum activity at 60oC, retained 100% of its original activities at 60oC for 2h, was maximally active at pH 7.0 and retained 100% of original activities at pH 9.0 for 2h. Enzyme activity was stimulated by urea, Mg2+, Ca2+ and Zn2+ but inhibited by Hg2+.

The climatological water balance (CWB) proposed by Thornthwaite and Mather (1957) is a useful tool for agricultural planning. This method requires the soil water holding capacity (SWHC), rainfall (R) and potential evapotranspiration (PET) data as input. Among the methods used to estimate PET, the one proposed by Thornthwaite (1948) is the simplest and the most used in Brazil, however it presents limitations of use, which is caused by its empirical relationships. When Thornthwaite PET method is used into the CWB, the errors associated to PET are transferred to the output variables, mainly water deficit (WD) and water surplus (WS). As all maps of WD and WS for Brazil are based on Thornthwaite PET, the objective of this study was to produce new maps of these variables considering Penman-Monteith PET. For this purpose, monthly normal climate data base (1961-1990) from Brazilian Meteorological Service (INMET), with 219 locations in all country, was used. PET data were estimated by Thornthwaite (TH) and FAO Penman-Monteith (PM) methods. PET, from both methods, and R data were used to estimate the CWB for a SWHC of 100 mm, having as results actual ET (AET), WD and WS. Results obtained with PET from the two methods were compared by regression analysis. The results showed that TH method underestimated annual PM PET by 13% in 84% of the places. Such underestimation also led to AET and WD underestimations of 7% (in 69% of places) and 40% (in 83% of places), respectively. For WS, the use of TH PET data in the CWB resulted in overestimations of about 80% in 78% of places. The differences observed in the CWB variables resulted in changes in the maps of WD and WS for Brazil. These new maps, based on PM PET, provide more accurate information, mainly for agricultural and hydrological planning and irrigation and drainage projects purposes.

Industrialization and urbanization has produced various types of wastes that sometimes are dumped in low-lying areas without proper treatment and engineering controls. Bangalore district has more than 60 illegal dumpsites consisting of either municipal or industrial waste. Government records indicate that more than 1,500 industries are working at various industrial areas and other locations around the city. In the present study an attempt has been made to characterize the Bommasandra industrial area dump site located at the south of Bangalore. This dump site is 15 to 20 years old and spreads on an area of 12.7 acres. Around 60 to 70 industries of all nature are located around this dump site. A large number of soil samples were collected and after site characterization of soil properties, an attempt has been made to predict the transport behavior of selected chemical species using available mathematical models and a program based on MATLAB- 7 to study the migration properties of these selected chemical species as a function of time. Also a model provided by USEPA DRASTIC has been used. The DRASTIC Index found for this dumpsite was 146; therefore, one can conclude that the studied dumpsite is moderately vulnerable to pollutants. The migrating behavior of cations such as sodium, calcium and anions such as sulphate, chloride were considered. It was observed that cations are better retarded in comparison to anions. This was attributed to exchangeable chemical reactions.

The degradation of water resources has been detected and changes both institutional and in the legislation have been demanded. The careless use of rivers has ecological changes as direct consequence, causing serious modifications in the landscape and fluvial regime, besides altering the availability of habitats and the trophic composition of the aquatic environment. Pressed by this scenario, scientists have been developing assessment methods that are efficient both for the evaluation itself and for supporting decision taking in the environmental management processes. In this perspective, the objective of this study is to present the Rapid River Assessment Protocols (RAPs) and to emphasize how these protocols can promote the community participation in water resources monitoring. The RAPs can used to evaluate in an integrated form the characteristics of a river section according to the conservation or degradation condition of the fluvial environment and it is characterized by its economic viability and easy applicability. In regions with poor financial resources and serious problems of water quality, the RAPs can be used in environmental management programs. By using these protocols, the integration of the community in water resources monitoring generates data which represent the quality of fluvial ecosystems throughout time, without requesting high costs or specialized professionals. The RAPs in a simplified but not simplistic tool, which can be used in activities that aim at promoting a quick and reliable assessment of the “health” of a river.

The 3 – indolyacetic acid is an important natural phytohormone in plants in low concentrations. The 3 – indolyacetic acid is involved in the regulation of many processes of growth and plants development. This study developed and validated an analytical method to quantify 3- indolyacetic acid using the Hight-Performance Liquid Chromatography with DAD detector. The following parameters were chosen: detection and quantification limits, linearity, calibration curve, precision, sensibility and assays of recovery. The calibration curve was obtained with five points based on standard solution. The method presented detection and quantification limits of 0.05 and 0.5 mg L-1, respectively. It showed linearity in the interval of 0.5 to 10 μg L-1 and correlation coefficients higher than 0.99. These results allow the conclusion that the method can be considered efficient and that it could be used to monitor 3 – indolyacetic acid in natural water.

In this paper we present data on soil microbial biomass and heterotrophic respiration in pastures, mature and secondary forests, in order to elucidate their contribution to total CO2 flux from soil to atmosphere. The research was conducted in Southwestern Amazonia, Acre State, Brazil. Microbial biomass was estimated using a variation of the traditional fumigation-extraction method and heterotrophic respiration was measured using respirometry flasks attached to an infrared gas analyzer. Soil microbial biomass and heterotrophic respiration did not differ statistically among pastures, mature and secondary forests. These laboratory results indicate that higher CO2 fluxes from pasture soils measured in situ are probably due to higher root respiration by pasture grasses.

Liners play an important role in minimizing migration of contaminants and are frequently constructed with natural materials serving as the primary barrier to contain chemicals and potentially harmful pollutants from municipal toxic waste leachates. To improve the performance of liners, additives like lime and cement at low percentages were added to Red Soil of Bangalore. Heavy metals like hexavalent chromium, copper and zinc and alkali metals like sodium and potassium were taken as contaminants. Batch leaching tests on 50 samples were performed according to ASTM D 3987 – 85 for soil and soil mixtures with contaminants. The heavy metals were potentiometrically monitored using ion selective mercury and platinum electrodes. The alkali metals were determined using a Flame Photometry. It has been observed that the retention of heavy metals elements followed the order copper> zinc>chromium over a period of 7 to 28 days. Chromium, zinc and copper attained equilibrium in this period as confirmed based on conductivity and pH data. Cement and lime had significant effect on copper and zinc. Specific adsorption of Cu onto CaCO3 surfaces may control Cu concentration in solution. Zn adsorption increases with pH; Zinc hydrolysed at pH > 7.7 and these hydrolyzed species are strongly adsorbed to soil surfaces. Cr was retained only by 50% and additives did not have much effect as it is subjected to nonspecific adsorption (temporary). Cr was found to be highly mobile in alkaline soils. It was observed that the retention of alkali metals follows the order: K > Na. Cement and lime had positive effect on the retention of Na and K. Sodium ion retarded immediately due to the removal of exchangeable cations, whereas potassium retarded more than sodium due to the lower hydrated radius of potassium. Scanning Electron Microscopy (SEM) characterization tests were performed to understand the soil mineral structure. Regular porous, sponge like, particles were detected in virgin soil containing crystals possibly of alumino sicilicate. Energy Dispersive Spectroscope (EDS) analysis indicated the presence of Si, Al, Ca, Ti, Fe, K, and Na. These results indicate the possibility of using Red Soil as an adsorbent.

Agriculture presents dependence on the climatic conditions, especially on precipitation. This way, it is necessary to study the probabilities of occurrence of rain in Garanhuns municipality, Pernambuco State, especially due to its irregularity, to support farmer’s decisions about agriculture activities. The objectives of this study were to forecast monthly rainfall at different significance levels and to determine the probabilities of occurrence of dry and rainy periods for Garanhuns region, state of Pernambuco, Brazil. Monthly rainfall data from 1913 to 1987 were analyzed. The criteria to identify dry and rainy periods were based on four classes of monthly rainfall: (S) dry month, from 0 to 50 mm; (PC) low rain month, from 50 to 100 mm; (C) rainy month, from 100 to 200 mm and (BC) very rainy month, above 200 mm. Thus, the monthly averages were analyzed according to the four classes of rains to estimate the probable occurrence of rain following Robertson (1976). The Gamma probability distribution was also used to forecast monthly precipitation, at the following levels: 90, 80, 75, 70, 60, 50, 40 and 30% of probability. The Gamma distribution adjusted well to the data of Garanhuns region, making possible the estimation of the probable rainfall amounts for each month of the year, at different levels of probability. Rainy season was the period between May and August, and the dry one between October and December. The lowest probable monthly rainfalls, below 50 mm, were observed between October and December, when irrigation is required for food production, being recommended to plant annual crops and cultivars of short cycle to be sowing in October, and of long cycle to be sowing in April, in order to reduce the risks of damage.

This work evaluated the effect of different levels of water into the soil and types of treated wastewaters from industries of Campina Grande city, Paraíba state, on the growth of castor bean plant, variety BRS Nordestina. The experiment was conducted in greenhouse of the National Center of Research of Cotton. The experimental design was in entirely randomized blocks with 15 treatments in scheme of additional factorial analysis [(4 x 3) + 3] with three replications, having the following factors: three types of treated wastewaters and water of provisioning (A1 = IPELSA - Industry of Cellulose and Paper of Paraíba S/A; A2 = COTEMINAS - Industry of improvement of cotton fiber S/A; A3 = ILCASA - Industry of dairy products of Grande S/A (LEBOM); A4 = Water of the network of public provisioning of Campina Grande city, three levels of available soil water (AW) (N1 = 100%, N2 = 80% and N3 = 70%) and three controls, one for each AW with water of provisioning and with inorganic fertilizer in the foundation (A4C). In order to evaluate the growth of the castor bean plant during a period of 135 days, biweekly measures of the plant height, diameter of the stem and total foliar area variables were accomplished. For all growth variables there were significant interactions among the studied factors, denoting the interdependence among them, what was reflected on the growth of the plants. The castor bean plant, variety BRS Nordestina, responded well to irrigation with treated wastewater, especially from COTEMINAS industry mainly when associated to the level of 100% of the available soil water.

This work studied in field the spatial distribution of discharge and pressure in subunit irrigated by microsprinkler, considering used and new emitters. The data were collected in 28 emission points spaced in 10 x 18 m. The mean values were submitted to normality test and also to a geostatistical analysis; the verification of the spatial dependence and of the interpolation was accomplished by the method of krigagem and the spatial continuities were studied by means of semivariograms for the discharges and pressures of the subunit with new and used microsprinklers. It is verified that the models varied if the emitter was new or used. The mathematical model that better adjusted to the discharge of the new and used emitters was, respectively, exponential and spherical; for the pressure, the model was the inverse of the discharge, that is, spherical for new emitters and exponential for used ones. The values for the used emitters of the nugget effect (Co), landing (Co+Cl) and reach (Ao) were of l.0 L h-1, 33 L h-1 and 218 m and of 0.43, 137 kPa and 58 m, for discharge and pressure, respectively. The coefficient of irrigation uniformity, the coefficient of uniformity of the system and the water application efficiency increased, respectively, in 11.9, 10.58 and 10.75%, when the used emitters were substituted by new ones. The maximum distance (reach) where the estimated data of discharge and pressure are spatially correlated extrapolated the length of the derivation line for the discharge with new and used microsprinklers and for the pressure only with new microsprinklers. The nugget effect for the pressure in the system was smaller when it was changed the used microasprinklers by new ones, the inverse was observed for the discharge. There was an increase in pressure as well as in discharge when the used microsprinklers were changed by new ones.

The rainfall-runoff process of the Pequeno River catchment, located in the Curitiba metropolitan region, Paraná State, Brazil was analyzed with two hydrological models, TOPMODEL and HYCYMODEL. Both models were applied to a series of 3360 hourly-observed rainfall-runoff data. The simulations of those models were compared in terms of total runoff generation and hydrograph separation. The uncertainty intervals were estimated for each model using the GLUE method. Both models presented a satisfactory and similar efficiency for the total runoff simulation. The ratio between total runoff and total precipitation was 0.79, 0.81 and 0.74 for the observed data, those calculated with TOPMODEL and with HYCYMODEL, respectively. The models also estimated a large quantity of the baseflow contributing to the total runoff (77.7% with TOPMODEL and 84.5% with HYCYMODEL), but there was a significant difference of those quantities between the models. The surface flow analysis showed that TOPMODEL considered that the catchment saturates and drains faster than HYCYMODEL.

Throughout 45 years (1958-2003) the solid wastes from João Pessoa were disposed off in the former Roger’s open dump, which is situated adjacent to the mangrove at the sides of Sanhauá river, intensifying environmental problems and threatening the health of people living nearby. Between 1999 and 2003 the decommissioned open dump received wastes from the cities of Cabedelo and Bayeux. Several environmental impacts result from this inadequate disposal of solid wastes, including the pollution of groundwater nearby the former Roger´s open dump, which is the major point of investigation of this paper. The water quality of 6 wells situated in the region of influence of the open dump were monitored. Results have shown that the groundwater near the open dump cannot be drunk by the population without previous treatment, since it has some parameters of water quality in discordance with Brazilian legislation concerned with drinking water. Results have also shown that the level of pollution is higher in the wells closer to the open dump.

A study was performed for investigating accumulation, distribution and toxicological effects induced by chromium (Cr) on the development of the mangrove seedling Kandelia candel (L.) Druce. Seedlings treated with increasing concentrations of CrCl3 solution (0, 0.5, 1, 1.5, 2, 2.5, 3 mg L-1, respectively) were grown in a basic nutrient solution for three months. The five month old seedlings were harvested for the experiment. This study showed that Cr treatment significantly decreased growth of K. candel in terms of seedling height, leaf number and total biomass. At the highest 3 mg L-1 Cr exposure, there was a 34.47% decrease in final seedling height, 68.95% decrease in leaf number and a 60.65% decrease in total biomass. The present study demonstrates that Cr accumulation ability of K. candel seedlings increased with the increase of treatment strength up to certain level. The concentrations of Cr in root, hypocotyl, stem and leaf ranged from 22.87 to 1.43 mg kg-1, 1.30 to 0.68 mg kg-1, 2.42 to 0.91 mg kg-1, and 1.74 to 0.74 mg kg-1, respectively. When comparing Cr concentration in different plant parts with respect to their controls, the results showed that treated plant root bioaccumulated high amounts of Cr. Almost 80% of Cr was accumulated mainly in roots. The distribution pattern of Cr in K. candel was Root > Stem > Leaf > Hypocotyl. Our findings indicated that the high concentration of Cr supply may interfere with several metabolic processes of seedlings, causing toxicity to plants as exhibited by chlorosis, necrosis, and finally, plant death.

The groundwater sources spread in extensive areas and are relatively protected from pollution agents when compared to rivers and artificial reservoirs. These aspects, combined with low exploitation costs, provided a considerable growth in the groundwater use in the last decades. Groundwater became an important alternative source for public water supply in Brazil. This paper shows the georeferenced location of the groundwater exploitation points in the Lajeado, RS municipality and the potability analysis of this water. The groundwater exploitation in the study area is accomplished in the Serra Geral and Guarani aquifers and the exploitation points were identified in field campaigns using a GPS receiver and plotted over satellite imagery using remote sensing and geoprocessing techniques. The groundwater potability assessment was based on 100 samples for microbiological and physico-chemical analyses that included 78 samples of tubular wells and 22 of dug wells. Contour maps were generated for the analyzed parameters in the tubular wells, using geostatistics procedures. In this study, 362 tubular wells and 253 dug wells were studied. The results show that the dug wells are located mainly in rural areas and 77.27% of them aren’t suitable for human consumption due to high levels of contamination. The tubular wells are concentrated in urban areas and results revealed that 76.92% of them have water with suitable quality for the human consumption.

Time Domain Reflectometry (TDR) is a reliable technique to estimate in situ moisture content in different types of materials using probes. The forest seedlings production implies in a comprehensive and empirical process of water management applied to the substrate used for cultivation in dibble-tube. This type of cultivation requires analysis of the physical characteristics of water and nutrients retention of the substrate. The main goal of this research was to develop and evaluate a TDR coaxial probe for rational management of water in the forest seedlings production. Initially, a physical validation of the probe was performed considering the following parameters: reflection coefficient, characteristic impedance and spatial sensitivity. Also, the performance of the probe was evaluated to estimate water content in laboratory conditions and we obtained a calibration curve for each type of porous material used. The results demonstrated the viability of TDR probes to estimate water content in soil and substrates.

The objective of this work was to analyze the spacetime variations in the trophic characteristics of the principal water bodies feeding Lake Mirim, in the state of Rio Grande do Sul, by determination of the Trophic State Index proposed by Toledo Jr. (IETT) and Lamparelli (IETL), to assess water quality data between 1996 and 1998. It was verified that the lotic environments presented greater eutrophication conditions when evaluated by the Toledo Jr. methodology, in which the IETT varied from Eutrophic to Hypereutrophic. However, the evaluated environments showed variations from Mesotrophic to Hypereutrophic for the IETL when evaluated according to the Lamparelli methodology. From the classification proposed by Toledo Jr., lentic water bodies were considered Mesotrophic (IETT > 44) and Hypereutrophic (IETT > 74), while the Lamparelli method classified them as Eutrophic (IETL > 59) and Hypereutrophic (IETL > 67). Concentrations of phosphorus encountered in all water samples were greater than the limits established by the CONAMA Resolution n. 357, 2005, for class 2 water bodies, probably due to the discharge of untreated domestic and industrial wastes into the waters.

Spatial analysis of diarrheal diseases in Vale do Paraíba, Brazil
Nascimento, Luiz Fernando Costa
UNITAU
The study of the spatial patterns of transmission of intestinal infectious diseases allows the development of methodologies to control the dispersion of these diseases. The aim of this study was to identify spatial patterns of hospitalization by diarrheal disease in the Paraíba Valley, Sao Paulo, Brazil, using geoprocessing techniques. The hospitalization records were obtained from DATASUS and analysed by rates, Human Development Index (HDI), sanitation and water coverage percentages; the data were analyzed using the TerraView software. The global Moran coefficient was used to identify spatial clusters. It was possible to identify a spatial cluster in the central region of the Paraiba Valley and in the region of the Mantiqueira Mountains. Correlation between hospitalization by diarrhea and other variables was not observed. The diarrhea is a multifactorial disease, but geoprocessing approach may provide subsidies to implement policies to minimize this problem for the public health service.

The Tapajós river is the main rivers of the Pará State and part of the Amazon basin is the largest world river basin, however, the population growth and development of agriculture in the region has generated the input of contaminants in this important river. The objective of this study was to evaluate the water quality of the Tapajós river in the presence of metals and physico-chemical parameters based on the CONAMA 357-05 resolution. Seven sampling stations were selected along the river in the surface, intermediate and bottom layers in low rainfall periods. The elements Ca, Mg, Al, Fe, Ba, Mn, Sr, Ti, Ag, Be, Cd, Co, Cr, Cu, Mo, Ni, Pb and Zn were determined using the inductively coupled plasma atomic emission spectrometry (ICP-AES), As was determined by ICP-AES with hydride generation, Hg was determined by cold vapor atomic absorption and the physico-chemical parameters were evaluated using various techniques. In almost all respects the elements Al and Fe are not presented in accordance with the values allowed by Brazilian legislation, with average values of 280.01 ± 294.69 ?g/L and 564.89 ± 326.5 ?g/L, respectively. There were excellent correlations between Ca and Mg, Ca and Sr, Mg and Sr, Mn and Ba, Sr and OD, Mg and OD. The Tapajós River showed high levels of Al and Fe that compromises the quality of this important river of the Amazon and can cause problems for the health of the population.

Knowledge of physical and hydraulic properties of soil is important for the appropriate use and management of soil, and for the understanding of dynamic movement process of water and solutes. This study aims to determine the soil infiltration capacity of the Concordia Experimental Basin, located in the municipality of Lontras in Santa Catarina state. The infiltration tests were performed with the concentric ring infiltrometer, with a diameter of 25 and 50 cm on twenty sampling points showing different uses of land and agricultural management practices. The initial capacity of infiltration, calculated by Horton's equation, ranged from 0.8 (pasture) to 5.0 cm min-1 (pine forest and cassava planting). In pasture areas, the initial infiltration ranged from 0.8 to 0.9 cm min-1. Regarding the minimum value, they ranged from 0.01 (perennial pasture) to 0.3 cm min-1 (minimum tillage for corn). In forest areas, the minimum infiltration varied between 0.05 and 0.15 cm min-1 and in the areas of pasture, it was equal to 0.01 cm min-1.

This work addresses some aspects related to the study of metals content evaluation from atmospheric precipitation considering both the fraction dissolved and the particulate matter in forest of Guarapuava region, PR. Samples of atmospheric precipitation were collected using collectors of total precipitation located inside and outside of a forest patch. Samples were collected during 12 months and the analyzed parameters were pH, conductivity, Al, Cd, Cr, Fe, Mn, Ni and Pb. The PCA (Principal Components Analysis) was performed and indicated that each rain event was responsible for the discrimination of samples from each sample collected within and outside the forest. Results of pH measurements revealed the occurrence of slightly acidic precipitation. Some metal had values above CONAMA nº 357 acceptance values. Toxic metals of anthropogenic origin were found demonstrating that weather phenomena contributed to the dispersion of pollution from urban areas.

Considering the fundamental role that the riparian vegetation plays in relation to maintenance of the environmental health of a watershed and the necessity of restoring sectors of the buffer zone without natural vegetation, in this paper we investigated what land cover classes occur along the riparian buffer stripes considered Area for Permanent Preservation (APP) in the Sorocaba municipality, SP in three periods: 1988, 1995 and 2003. Based on GIS technology and using the drainage network map, the APP stripes (riparian buffer zones) map was generated, and this map was overlaid to the land cover map (1988, 1995 and 2003) to provide a land cover map specifically of the riparian buffer zones. The results show that 58.43% of the APPs have no land cover of native vegetation and therefore, need to be reforested, representing 5,400 hectares to be restored.

In this work it is presented the results of bench scale tests using Advanced Oxidation Process (AOP) in a UV/H2O2 system, for the treatment of an industrial effluent with a high concentration of dissolved organic matter, resulted from thermal treatment of oil-water emulsions. Treatability tests were carried out in a batch photochemical system with recycle, and the raw effluent was characterized by the analysis of pH, turbidity, color, COD and TOC. Results from these assays shown that UV/H2O2 process is technically feasible resulting in TOC removal above 90%. However, for one log TOC removal from this effluent the energy required was about 455.5 kw.h.m-3, for an alpha relation of 10 mg H2O2/mg COT, resulting in a higher operational cost, considering the evaluated conditions.

In this study the composition and diversity of aquatic macroinvertebrates were evaluated in the reservoir of water captation of Batalha river for treatment and supplying of the city of Bauru. The samples were collected in dry (from June to August, 2005) and rainy (from December, 2005 to February, 2006) seasons. We analyzed and identified 840 organisms belonging to 8 taxa in dry season and 4 taxa in rainy season. The system presented low abundance and diversity of macroinvertebrates probably due to the water quality and its physical and chemical variations associated with rain events.

Since the mid 80's, the riverside population of Rio Botafogo, in the Santa Cruz channel, Itamaracá has undergone critical environmental situations due to poorly planned growth and inadequate soil occupation, and as a consequence, a loss in environmental quality resulted. In 1963, an industry for production of chlorine and caustic soda produced by electrolytic cell of mercury was installed in the Botafogo river. By mid-1987, a discharge of inorganic mercury between 22 and 35 tones of mercury in this river was estimated. In addition to this industry, others of different types were installed in recent years along the sides of this river. Based on previous studies, we conducted a new assessment of contaminated sites, comparing the changes over the years concerning the quality of water and sediment of the Botafogo river, in which the locations of collection, the need to increase the network of environmental monitoring were investigated. The parameters defined for analysis of water were: pH, dissolved oxygen (OD), biochemical oxygen demand (BOD), ammonia and phosphorus concentration, color, turbidity and mercury content. It was monitored the concentration of mercury in the sediments. The values of pH, turbidity, DO, BOD and ammonia usually showed values within the limits established by CONAMA Resolution No 357. Color parameters have remained consistently high, probably caused by continuous withdrawal of sand before the points of collection. The content of phosphorus was high, until the beginning of 2005, and remained within standards required by legislation until the end of this research. In the studied area, it has been installed, since 1963, an industry for chlorine and caustic soda production, which uses in its manufacturing process electrolytic cell of mercury. In this experiment, the impact of mercury has been observed.

Feasibility of a daly of no more than 10-4 per person per year for water reuse in agriculture, in developing countries
Hespanhol, Ivanildo
Universidade de São Paulo
DALYs are a measure of the health of a population or burden of disease due to a specific disease or risk factor. It evaluates the time lost because of disability or death from diseases compared with a long life free of disability in the absence of disease. DALYs are calculated as the sum of years of life lost by premature mortality (YLL) and years of healthy life lost in states of less than fully health, i.e., years lived with a disability (YDL), which are standardized by means of severity weights, thus: DALY=YLL+YLD. WHO has established for wastewater use in irrigation the same reference level of health protection as established for drinking water quality, i.e., the additional burden of disease from consuming water irrigated food should not exceed 10-6 DALY (Disability-Adjusted Life Years) loss per person per year (pppy). Such a restrictive risk is almost impossible to be attained in most developing countries which may not be able to afford the cost of wastewater treatment and of other protective measures, even for restrict irrigation. This paper analyses which protective measures are able to be implemented in developing countries and proposes a tolerable disease burden of no more than 10-4 DALY per person per year. In order to evaluate this proposal it is mandatory to adopt a methodology of cost/benefit, through the development of epidemiologic studies and the identification of local characteristics and constraints, particularly the ones related to public health, technical, socio economical and environmental conditions.

The waterfront of Belém, the capital of Pará State, Brazil, has undergone a beautification process whereby a hydraulic embankment is being executed at a section located at the confluence of the Guamá River and the Guajará Bay. A two-way avenue and a leisure and tourist complex will be built on this filled area. Protection of the construction site may be required in order to minimize loss of material during the build up operation and it could serve to maintain the tourist complex as well. Other important point is the impact analysis of the construction on the global flow at the confluence of the Guamá River and the Guajará Bay. Thus, a two-dimensional hydrodynamic finite elements model is used to simulate the velocities in the region for three configurations, namely: the first with the natural configuration of the area; the second where the work area is being protected by one groin; and the third one with two groins. The flow simulation for flood tide or ebb tide showed that for flood tide the velocities are higher than those in ebb tide. The simulated velocities with the presence of groins are slower than those simulated with the natural configuration model. Thus, it shows the efficacy of the groins to slow down the currents` velocities. In addition, the groins could protect the section of the revitalized Belém shore. In a general way, the construction does not change the global flow in the region.
