Abstract The present study aims to assess the aquifers and delineate the subsurface structures which control the aquifers' geometry using geoelectrical and ground magnetic data. Twenty-four vertical electrical soundings were measured and interpreted, revealing six geoelectrical layers that range in age from the Middle Eocene to Quaternary. The freshwater aquifer exists in the Upper Miocene section and represents the primary source for drinking water and domestic utilizes. The freshwater aquifer has a thickness ranging from 19 to 49 m. It lies at a depth ranging between 2 and 10 m. The brackish water aquifer coincides with the Middle Miocene section and represents a valuable water source for industrial uses. The preferable zones for drilling new water wells correspond to the eastern, northwestern, and southwestern areas. One hundred twelve ground magnetic stations were measured with a spacing interval of 200 m and interpreted to determine the basement depth and detect the fault systems that dissect the area. The magnetic data interpretation indicates that the basement depth is shallow at the western part and increases toward the eastern part, reflecting a thickening of the sedimentary cover at the eastern side. The magnetic data also reveals that the aquifers' geometry and the subsurface setting are controlled by the NW-SE, NE-SW, and N–S structural trends.

使用地电和磁数据的地下水存在潜力：以埃及东部沙漠北部南部 Wadi Hagul 地区为例

摘要 本研究旨在利用地电和地磁数据评估含水层并描绘控制含水层几何形状的地下结构。对 24 次垂直电测深进行了测量和解释，揭示了年龄从中始新世到第四纪的六个地电层。淡水含水层存在于上中新世部分，是饮用水和家庭用水的主要来源。淡水含水层的厚度为 19 至 49 m。它位于 2 到 10 m 之间的深度。咸水含水层与中中新世部分重合，是工业用途的宝贵水源。新水井钻探的优选区域对应于东部、西北和西南地区。以 200 m 的间距测量了 112 座地面磁站，并对其进行解释以确定基底深度并检测剖析该区域的断层系统。磁资料解释表明，基底深度在西部较浅，向东部增加，反映了东部沉积盖层的增厚。磁性数据还表明，含水层的几何形状和地下环境受 NW-SE、NE-SW 和 N-S 结构趋势控制。反映了东侧沉积盖层的增厚。磁性数据还表明，含水层的几何形状和地下环境受 NW-SE、NE-SW 和 N-S 结构趋势控制。反映了东侧沉积盖层的增厚。磁性数据还表明，含水层的几何形状和地下环境受 NW-SE、NE-SW 和 N-S 结构趋势控制。
