A surface water contamination vulnerability mapping has been carried out to contribute to water quality protection of the Martil river dam. The applied methodology (ESU) depends on three parameters i) density of the hydrographic network ii) soil hydrologic potential and iii) agricultural drainage. The vulnerability degree is a result of a typological interaction between these three parameters through there different possible combinations Results indicate that high vulnerability classes are shown within almost 85 %of the catchment area. Otherwise, some southern, northern and south western areas (14 %) are of mean vulnerability, while a very restricted area (1 %) shows low vulnerability to contamination.

Abstract: (french)
Afin de contribuer à la protection de la qualité de l'eau du barrage de l'oued Martil, il a été objet d'une cartographie de la vulnérabilité à la contamination des eaux de surface par des produits polluants. La méthode appliquée est la méthode ESU ; celle-ci dépend de trois paramètres i) la densité du réseau-hydrographique ii) le fonctionnement hydrique des sols et
iii) le drainage agricole. Le degré de vulnérabilité est le résultat du croisement typologique des classes de ces trois paramètres à travers des différentes combinaisons possibles. Les résultats obtenus montrent que les classes de vulnérabilité très forte et forte envahissent environ 85% du bassin versant. La première recouvre presque la totalité du bassin de Martil, à l'exception de sa partie est où domine la classe forte. Pour la classe de moyenne vulnérabilité, avec 13,7% de surface totale de la zone d'étude, elle marque le Sud, le Sud-ouest et le Nord du bassin. Finalement, vers le Sud et le Sud Est, se localise la classe de faible vulnérabilité avec une superficie de l'ordre 1,37%.
