Groundwater is a valuable shared resource in the Moulouya Basin, but it has been in decline due to recent years of low rainfall and rapid population growth. To support socio-economic development, there is increased demand for this precious resource. This paper presents a standard methodology for delimiting potential groundwater zones using geographic information systems (GIS), an integrated analytical hierarchy process (AHP), and remote sensing techniques. Seven parameters that monitor the presence and mobility of groundwater, including drainage density, lithology, slope, precipitation, land use/land cover, distance to river, and lineament density, were incorporated into a raster data model using ArcGIS software. AHP-based expert knowledge was used to prepare a groundwater potential index and assign weights to the thematic layers. The study classified the area into five zones of varying groundwater potential: very high (26%), high (51%), moderate (13%), poor (9%), and very poor (1%). The accuracy of the model was validated by comparing the Groundwater Potential Zones map with data from 96 wells and boreholes across the basin. The validity of the results was confirmed by comparing them with the specific yield of the aquifer in the study area, yielding a high correlation coefficient (R²) of 0.79. The analysis revealed that 89.5% of the boreholes were situated in the high and very high potential zones, demonstrating the reliability and robustness of the employed approach. These findings can aid decision-making and planning for sustainable groundwater use in the water-stressed region.

地下水是穆卢亚盆地宝贵的共享资源，但由于近年来降雨量少和人口快速增长，地下水一直在减少。为了支持社会经济发展，对这一宝贵资源的需求不断增加。本文提出了一种使用地理信息系统（GIS）、综合分析层次过程（AHP）和遥感技术来划定潜在地下水区域的标准方法。使用 ArcGIS 软件将监测地下水的存在和流动性的七个参数（包括排水密度、岩性、坡度、降水、土地利用/土地覆盖、到河流的距离和线性密度）纳入到栅格数据模型中。基于层次分析法的专家知识用于制定地下水潜力指数并为专题层分配权重。该研究将该地区分为五个不同地下水潜力的区域：非常高（26%）、高（51%）、中等（13%）、差（9%）和非常差（1%）。通过将地下水潜力区图与流域内 96 口井和钻孔的数据进行比较，验证了模型的准确性。通过与研究区含水层的比产量进行比较，证实了结果的有效性，相关系数（R ²）高达0.79。分析显示，89.5% 的钻孔位于高潜力区和极高潜力区，证明了所采用方法的可靠性和稳健性。这些发现可以帮助缺水地区可持续地下水利用的决策和规划。
