%X The hydric erosion is considered as one of the most serious problems related to hydric resources conservation.Hence the need for prediction mechanisms made with the aid of modeling. There are several methodologicalapproaches with the objective of modeling the erosive potential of a given region, among which there are thosethat analyze and evaluate several landscape variables based on an integrated approach. The objective of thispaper was to elaborate a spatial dynamic modeling for monitoring and predicting silting-up processes based onthe Modified Universal Soil Loss Equation (MUSLE) in the Capivara river watershed, city of Botucatu-SP, usinga Cellular Automata approach, in the Dinamica EGO plataform. The model was driven by orbital Landsat 5 TMimagery used for mapping the land use and land cover for 1987, 1997, and 2007, topographic maps issued, thesoftware ENVI 4.7and ArcGIS 10. Among the reached results, we shed light over land use and land cover anderosion maps produced for 1987, 1997 and 2007 with prospective scenarios for 2017. It was noticed anincreasing in potential volumes of erosion overall the areas of drainage and cuesta related to a decreasing ofbushes class in this regions. Considering the downstream regions, it was observed a decreasing of values relatedto erosion scenarios, overall by the replacement of grasslands by reforesting and citrus along the analyzed period(1987-2017). It shows clearly that land use and land cover changes influence directly in sediment yield in thewatershed, and can be simulated with probabilistic scenarios.
