Short summary
The Moulouya watershed presents high risks of water erosion. The dams built on this river lose 10Mm3 of water every year. This worrying rate shows that water erosion can hinder the socio-economic development of the basin. This study defines the areas most threatened by water erosion. Using a GIS and the USLE, we mapped soil losses. The adopted model determines soil loss from erosivity of rainfall, soil erodibility, inclination and slope length, soil cover, and erosion control practices.
