摘要：

Assessing the degree of vulnerability of surface water intended for drinking water supply has become a major necessity in water resource management and decision-making; it allows to identify high-risk areas and provide all the necessary measures for its protection. Specialized analysis techniques using geographic information systems (GIS) and remote sensing are increasingly being used to qualitatively assess this vulnerability. For his purpose, the aim of this study is to present the results of the application of the “DKPR” approach for evaluating of the degree of vulnerability that concerns water contamination of the Ghiss dam sub-watershed, a hydraulic structure under construction to ensure the supply of drinking water to the city of Al Hoceima and the surrounding centers, as well as the protection of the downstream area against floods generated during the Ghiss river floods. The latter drains agricultural plots, natural areas, uncultivated land, and rural settlements. The approach adopted involves four parameters: accessibility of the aquatic environment (D), soil and subsoil water functioning (K), watershed physiography (P), and rainfall erosivity (R). The final result is a map obtained by additionally combining the index maps of these four parameters. The overall vulnerability index obtained by this combination varies in a range of values from 0 to 4 and is divided into five classes of vulnerability ranging from “very low” to “very high.” The results achieved show that the Ghiss dam sub-watershed is dominated by the moderate vulnerability class. It occupies 59.63% of the total area of the sub-watershed studied. © 2021, Saudi Society for Geosciences.
