Groundwater is under constant threat of exploitation with increasing demands. Therefore, there is a need for more advanced methods for exploring potential groundwater zones to meet people requirements. Groundwater in hard terrain areas is present in fractured zones, whereas in lateritic terrain it occurs in layered strata. Electrical resistivity tomography (ERT) is an advanced geophysical technique used in our present study; a quasi-3D ERT survey was conducted using different arrays. 2D Geophysical data were acquired along 18 ERT profiles of Wenner and Wenner–Schlumberger arrays and 13 ERT profiles of Dipole–Dipole array. Each profile of 200 m length was kept parallel to each other at 5 m spacing in the E–W direction. The inverted response was generated and, based on resistivity distribution, different geological layers of clay, sand and laterite were delineated using various ERT arrays. A conductive zone was marked as a potential aquifer zone at depths of 7–10 m below ground level. Thus, the quasi-3D geoelectrical approach was applied successfully in a lateritic environment for deciphering potential groundwater zones.

随着需求的增加，地下水不断受到开采威胁。因此，需要更先进的方法来探索潜在的地下水区以满足人们的需求。硬地地区的地下水存在于断裂带中，而在红土地区则存在于层状地层中。电阻率层析成像（ERT）是我们目前研究中使用的一种先进的地球物理技术；使用不同的阵列进行了准 3D ERT 调查。二维地球物理数据是沿着 Wenner 和 Wenner-Schlumberger 阵列的 18 个 ERT 剖面和偶极-偶极阵列的 13 个 ERT 剖面获得的。每个 200 m 长的剖面在 E-W 方向上以 5 m 的间距相互平行。生成了反演响应，并且根据电阻率分布，粘土的不同地质层，沙子和红土是使用各种 ERT 阵列来描绘的。在地平面以下 7-10 m 深处，一个导电区被标记为潜在的含水层。因此，准 3D 地电方法成功地应用于红土环境中，以破译潜在的地下水区。
