Title : MODELLING OF SOIL EROSION PROCESSES AND RUNOFF FOR SUSTAINABLE WATERSHED MANAGEMENT: CASE STUDY OUED EL ABID WATERSHED, MOROCCO
Abstract : The study was carried out in the watershed of Oued El Abid that is located upstream of the Bin El Ouidane Dam in Morocco. Looking for a sustainable watershed management practices, we estimated soil losses from the river basin and the sediment yield deposited in the dam of Bin El Ouidane, using the Intensity of Erosion and Outflow - IntErO model, based on the Erosion Potential Method - EPM. The watershed of the lake receiving the waters and sediments from the two mean water courses Oued El Abid and Assif Ahansal, therefore before to proceed the calculation, the watershed was divided in two sub basins; the soil erosion and sediment yield were calculated for each sub basin. The result of calculation for the studied Oued El Abid river basin showed that the production of erosion material in the river basin is 3.960.115 m³yr-1. Coefficient of the deposit retention, calculated using the IntErO model, was 0.3 and as a consequence, real soil losses were calculated on 1.188.657 m³yr-1; specific real soil losses per km2 402 m³km2yr-1. Our findings, based on Gavrilovic classification, pointed out that the studied area is with a medium potential of soil erosion risk, due to the steep land slope and low vegetation cover in the watershed. The model outcome is validated using the Bathymetry measurements in the Dam of Bin El Ouidane.
