| الوصف: | This work is inscribed in the general problem of analysis and modeling of water erosion phenomenon. Its aim is to determine the erosion rate in the Khmiss watershed (Northern Morocco). This erosion modeling was performed using the US LE hydrological model (Universal S oil Loss Equation) integrated into a Geographic Information S ystem (GIS ) platform and adapted to Moroccan con ditions. The modeling of erosion in the Khmiss watershed required the evaluation of various factors of the US LE over the entire drainage area and their expression in the form of thematic maps. This is a multiplicative function of five factors that control water erosion: rainfall erosivity, soil erodibility, slope gradient and length, vegetation cover and erosion control practices. The multiplication of those factors allowed us to produce a quantitative map with an average rate of erosion of 36t/ha/year. The description of the resulting map shows that areas with low erosion ( 120t/ha/year) cover only 8% of the basin area. A comparative analysis was conducted to highlight correlations between erosion rates and the various factors of this process. |
