Potential Soil Erosion Modeled with RUSLE Approach and Geospatial Techniques (GIS Tools and Remote Sensing) in Oued Joumouaa Watershed (Western Prerif-Morocco)

Water erosion is a complicated phenomenon that contributes to soil degradation and linked natural anthropogenic causes are difficult manage in time space. It has significant impact on our country necessitates number of studies efforts prevent it. Geospatial approaches (GIS tools remote sensing (RS) data) were used test the RUSLE strategy Joumouaa watershed, where it was found be accurate. The latter mountainous range with 60 km² area part Western Prérif Teroual region (northern Morocco). proposed technique integrates for calculating geospatial techniques detecting variables cause water loss. erosivity factor R had values, an average 1832.76 1968.87. shown soils erodibility k 0.016 0.0245, which indicates they most vulnerable. With upstream being rougher more sensitive, LS ranged from O than 43%. According nature land, there different C factors. affects all regions basin varying degrees, depending processes erosion. results show watershed medium highly erodible, maximum ranging 50 280 t/h/year, sparse plant covers little protection, moderate high climatic aggressiveness. An understanding danger may gained this study, as well guide land management planning can construct decision support tool terms resource management.
