Water erosion is a natural process that is intensified by the lack of conservation practices, soil vegetation cover misuse and removal. It has as a consequence, soil impoverishment, silting and water bodies eutrophication, among others. Importance fundamental to erosive processes become aware so that decision makers adopt mitigation and/or prevention measures for this phenomenon. The USLE enters as a tool to soil loss by laminar erosion estimate. The Geographic Information Systems (GIS) use has been shown efficient to erosive susceptibility characterize, due to the ease of data collection. Many of these are available for free, such as QGIS software and environment dates. This project aimed to map and qualitatively analyze the Curral de Arame Watershed erosive susceptibility, using free GIS and environmental dates. Annual soil loss estimating values under study ranged from 0 to 389 tons per hectare per year. The greatest influence factor observed was CP factor - Use and Management and Conservation Practices, due to the region moderate slope.
