Abstract:Adopt a basin as a hydrological unit to understand the physical processes related to the water and sediment production is important because its characteristics (area, shape and topography) can determine its use in a sustainable manner. This study is aim in the test of the applicability of hydrologic model SWAT (Soil and Water Assessment Tool) in the Tijucas River Basin to quantify the water and sediment production along it sub-basins. Together, geoprocessing techniques were applied with the creation of a database of geographical information to describe the region. On this database is included the daily precipitation an temperature data of the gauges distributed on the watershed, soil data, a land use map and the digital elevation model (DEM) to create the Hydrologic Response Units (HRU’s). A time series with flow values and sediment concentration measured are very important to calibrate and validate the model output parameters. After the calibration of the initial results, the Flow Gauge number 102 presented a Nash and Sutcliffe Coefficient - COE = 0.6 indicating a good adjust of the model. The results were used to create a sediment production map for Tijucas River Basin, when the 10 years average ranged between 0.5 ton/ha and 9.0 ton/ha in some sub-basins.
