Abstract

The watershed of Wadi Boumoussa (high Chaouia, La Meseta , Morocco ) is characterized by a sub-Mediterranean climate. Erratic rainfall, combined with a significant agricultural mechanization, causing damage". Severe erosion. Soils are increasingly degraded.The integration of thematic maps of various factors of universal soil loss equation in the Geographic Information System (GIS - Mapinfo) with their databases, allowed a fast and effective way to unravel the complexity and the interdependence of the factors in the analysis of risk of erosion, to better understand the impact of each factor and to assess its contribution to soil loss. Integration into the GIS formulas of universal soil loss equation has produced a synthetic map of the distribution of degrees of tb (DGDC erosion, determines the rate of erosion by sheet runoff ( 25t / ha / year on average) and to establish the key factors that control water erosion are , in order of importance , slope, soil erodibility and vegetation cover . This work can be used to calculate the erosion potential in other similar basins in the plains and plateaus experiencing sheet erosion " sheet erosion".
