Abstract

Soil erosion and sediment transport have been modeled at several time scales. In this study, we propose a power-type model (Qs=a.Qlb) with (R² = 0,77) linking the liquid flow rate to the suspended solid flow rate that was tested at different time scales to quantify the specific degradation at the basin scale. Oued Allalah (293 km2). The results of this test show that the average specific degradation is of the order of 11.08 t∙ha∙year-1. This modeling will be applied to the reconstitution of missing data at the Hydrometric station of the basin.
