Hydrology and Watershed Management Studies

The water resources management has driven researches, which search for alternatives to the understanding about processes occurring in river basins.Therefore, this study aimed to apply the SWAT model (Soil & Water Assessment Tool) as complementary tool for water resources management.The model was used in Apeú River Basin, from 2009 to 2017 to obtain information on the hydrological cycle dynamics based on climatic variables, type and land use.This kind of information can help in the planning of water resources management.During the model calibration, it obtained good efficiency (Nash--Sulticliffe) with a value of 0.89 which was achieved by the correlation (R² = 0.99) between the simulated and observed values and by the low error values during the flow simulation.These results showed that the model can help in the generation of information for areas without monitoring, and consequently it can help the best planning of water resources for basins.
