Integrated Environmental Management and Planning based on Soil Erosion Susceptibility Scenarios

Abstract This article presents the identification of soil use potential for different agropastoral and forest scenarios, using an indicator erosion susceptibility from spatialized Universal Soil Loss Equation (USLE). All USLE factors were ArcGis 10.5 software, case study Cachoeira Cinco Veados Watershed-RS. To determine R factor, we used Cassol et al. 2007 equation a 33-year series rain data six climatic stations. For K published values classes: Entisol, Ultisol, Oxisol, Molisols used. From DEM, LS factor was obtained, considering slope classes (0-3, 3-8, 8-20, 20-45, 45-75, >75%). In addition to actual land situation in watershed, nine scenarios proposed C factor. The value 0.5 evaluation conservation practices (P factor). Considering current along with other results showed that, by identifying most susceptible areas each scenario, it is possible construct map compatibilities use, sustainable limits losses. Therefore, this resulting has as instrument planning zoning studies.
