The Mediterranean mountains of Morocco are faced with numerous erosion problems: topsoil scouring through sheet (1 to 5 t/ha/year), rill (10 to 100 t/ha/year) and tillage erosion (1 to 60 t/ha/year), gully erosion on hill slopes (100 to 300 t/ha/year), landslide and embankment degradation around wadies, floods and reservoir siltation. Linear erosion being more important than sheet erosion on steep slopes, runoff energy is more important on the mountains than rainfall energy.
