چکیده
The present study aims to estimate the soil losses in watershed of Oued Amter extends length internal Rifain domain, located region Tangier-Tetouan-Al Houceima, Chefchaouen province north-western Morocco. spatialization empirical model was based on integration five factors Geographic Information System, namely, rainfall erosivity, erodibility, vegetation cover, topography and anti-erosion practices, whose superposition allowed elaboration quantitative map at scale. covers an area 300 km2 ; it is elongated with altitude ranging from 0 m 2100 north south a slope that varies 58.58%. climatic stations near has shown irregularity time space. erosivity factor R presented values 1637.09 1937.61, average 1787.35 Mj.mm/ha. h. (Millijoule. Millimeters/hectare. Hour. Year). erodibility K presents 0.139 0.140 showed soils little evolved Vertisols are most vulnerable erosion.
