Delineation of Groundwater Potential Area using an AHP, Remote Sensing, and GIS Techniques in the Ifni Basin, Western Anti-Atlas, Morocco

An assessment of potential groundwater areas in the Ifni basin, located western Anti-Atlas range Morocco, was conducted based on a multicriteria analytical approach that integrated set geomorphological and hydroclimatic factors influencing availability this resource. This involved use geographic information systems (GIS) hierarchical process (AHP) models. Different were classified weighted according to their contribution impact reserves. Their normalized weights evaluated using pairwise comparison matrix. Four classes potentiality emerged: very high, moderate, low, occupying 15.22%, 20.17%, 30.96%, 33.65%, respectively, basin’s area. A map (GWPA) validated by with data from 134 existing water points receiver operating characteristic (ROC) curve. The AUC calculated at 80%, indicating good predictive accuracy AHP method. These results will enable operators select favorable sites high potential.
