ResumoThis 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, Santos, C.
