Groundwater demand has dramatically increased due to the swift demographic explosion, especially in arid areas, where groundwater is considered the main source for all purposes. Thus, this research integrates climatological, lithological, structural, topographical, hydro-morphological, and geoelectrical data to explore groundwater potential zones in the central part of Sinai Peninsula, Egypt using the GIS-based Analytic Hierarchy Process (AHP). Seven thematic layers of soil moisture, rainfall, normalized difference vegetation index, drainage density, lineament density, slope, and land use/land cover were built from different remote sensing data sets. The eighth layer represents a high-resolution lithological map of the study area, constructed utilizing the power of the support vector machine over Sentinel 2 data and accurately assessed with a previously published geological map. Ground Water Potentiality Map (GWPM) was constructed and highlighted four main areas as promising zones. Comprehensive geoelectrical analysis was executed through seventeen deep vertical electrical soundings (VESs) using Schlumberger configuration, isoresistivity mapping, and geoelectric cross-sections along five different profiles. 3D view of the studied area's subsurface geological and structural pattern with groundwater flow direction specification, and adequate aquifer characterization, revealed four main geoelectrical units. Geoelectrical data results reasonably coincided with remote sensing data findings in highlighting three freshwater potential zones. Furthermore, the study strongly recommends integrating low-cost remote sensing datasets in narrowing the zone to be intensively investigated using further costly geophysical approaches or drilling test boreholes.

由于人口的迅速增长，地下水需求急剧增加，特别是在干旱地区，地下水被认为是所有用途的主要来源。因此，本研究整合了气候学、岩性、结构、地形、水文形态和地电数据，使用基于 GIS 的层次分析法 (AHP) 探索埃及西奈半岛中部的地下水潜力区。从不同的遥感数据集构建了土壤水分、降雨量、归一化植被指数、排水密度、线状密度、坡度和土地利用/土地覆盖等七个专题层。第八层代表研究区的高分辨率岩性图，利用支持向量机对 Sentinel 2 数据的强大功能构建，并使用先前发布的地质图进行准确评估。构建了地下水潜力图 (GWPM)，并强调了四个主要区域作为有希望的区域。使用 Schlumberger 配置、等电阻率映射和沿五个不同剖面的地电横截面，通过 17 次深垂直电测深 (VES) 执行了全面的地电分析。研究区域的地下地质和构造模式的 3D 视图以及地下水流向规范和充分的含水层特征，揭示了四个主要的地电单元。地电数据结果与突出三个淡水潜力区的遥感数据结果合理地吻合。此外，
