La cartographie de la vulnérabilité à la contamination des eaux de surface du bassin versant du Barrage de I'Oued Martil

This work present a document allowing a good management territorial of the watershed of Martil river situated in the Wilaya of Tétouan, (North of Morocco) to preserve the good quality of the water of the dam. Such document is developed by applying the DKPR method to map the degree of vulnerability in the contamination surface water by means of a software GIS. The obtained map shows the dominance of the high and moderate classes. The first one covers the central part of the of the studied area on approximately 50 % of the total surface, while the moderate class disparate on all the watershed while being more concentrated towards the Southwest and the East, concern almost 42 % of the studied area. Let us indicate that the extreme East of the watershed nearly 8% of the total surface is weakly protected against the contamination of its superficial water resources.
