This research intended to discuss methods to simulate characteristic hydraulic times (CHT) in a natural body with focus on Residence Time, Times of Renewal Rates and Water Age. The water body chosen is the Patos Lagoon located in southern Brazil considered the largest choked coastal lagoon in the world with over 300 km in length and an average width of 40 km. The figure shows the results of Water Age simulation for dry and wet seasons. The results show clearly the influence of river inflows in the northern part, and the influence of tides in the southern part.
