In the Isly basin, an arid region in Morocco, access to water resources is a key factor in its socio-economic development. The purpose of the present study is to contribute to the search for areas suitable for the establishment of productive water wells by mapping areas that have the potential to provide a suitable water supply. The mapping process used a conceptual model of the factors that are controlling the distribution of groundwater in the region together with the use of remote sensing methods and a geographic information system (GIS) to cover the entire region (920 km²). Data on five parameters influencing groundwater storage (rainfall, lithology, rock fracture, slope, and drainage) were integrated into an empirical model and validated using well discharge data and the location of springs. Results show that the survey area is potentially rich in groundwater, with over 60% of the Isly basin having a “moderate” to a “very high” potential for groundwater storage. The empirical model makes up an important decision support tool since it allows suitable groundwater drilling targets to be identified.

在摩洛哥的干旱地区伊斯利盆地，获得水资源是其社会经济发展的关键因素。本研究的目的是通过绘制有潜力提供合适水源的区域来帮助寻找适合建立生产性水井的区域。制图过程使用了控制该地区地下水分布的因素的概念模型，并使用了遥感方法和地理信息系统（GIS）来覆盖整个地区（920 km ²）。将影响地下水存储的五个参数（降雨，岩性，岩石破裂，坡度和排水）的数据整合到一个经验模型中，并使用井水排放数据和泉水位置进行验证。结果表明，调查区域可能富含地下水，伊斯利盆地60％以上的区域具有“中等”至“非常高”的地下水储存潜力。由于经验模型可以确定合适的地下水钻探目标，因此它是重要的决策支持工具。
