The figure shows a shaded relief geological map of a portion of the Sanfranciscana Basin underneath which is located the Urucuia aquifer, the main focus of this research. In the figure, it is highlighted the area modeled with boundary conditions, climatological and groundwater observation stations, and stratigraphic wells. Based on the simulation of groundwater flow in steady-state, the results of this research point to a greater impact on surface water caused by a reduction in groundwater storage and related river base flow.
