MODELING OF SOIL WATER EROSION IN OUED CHERRAT WATERSHED (MOROCCO) BY APPLYING THE UNIVERSEL SOIL LOSS EQUATION (USLE)

IN THE CURRENT STUDY, THE U NIVERSEL SOIL LOSS EQUATION (USLE) IS APPL IED TO MODELING THE SOIL WATER EROSION IN OUED CHERRAT WATERSHED LOCATED IN THE WEST OF MOROCCO. USLE MODEL TAKES IN CONSIDERATION THE MA IN FACTORS THAT I NFLUENCE WATER EROSION : RAINFALL, TOPOGRAPHY, SOIL PROPERTI ES, THE CONDI TIONS OF CROP MANAGEMENT AND CONSERVATION PRACT ICES. MANY DATA, FROM VARIOUS SOURCES WAS USED THROUGH THE SPATIAL TOOLS, GIS (GEOGRAPHIC INFORMATION SYSTEMS) AND REMO TE SENSING, TO AS SESS THE RISK OF WATER EROSION. THE RESULTS SHOW THAT 65 .7% OF THE STUDY AREA HAS A VERY LOW RISK OF ERO SION, 7 .7% LOW R ISK, 9.9% MEDIUM RISK, 5.4% HIGH RISK AND 11 .3% A VERY HIGH RISK. THE SOIL LOSS VARY BETWEEN 0 AND 524 .15 T/HA/YR. THE AVERAGE RATE OF EROSION FOR THE ENTI RE WATER SHED I S ESTIMATED TO 12.16 T/HA/YR. PRIORITY AREAS FOR EROSION MANAGEMENT REPRESENT 16. 7%. GENERALLY CHARA CTERIZED BY HIGH SLOPES, THEY ARE MAINLY LOCATED IN THE UPSTREAM OF THE WATERSHED AND ON THE BANKS OF OUED CHERRAT AND ITS STREAMS.
