“…Iso-resistivity maps are useful in understanding lateral change in electrical resistivity. Resistivity change with depth is easier studied when iso-resistivity maps are generated and compared for different depth (El-Sayed et al, 2023). The iso-resistivity map 6, 30, 50, 100, 150 and 200 m depth is presented in Figure 6.…”

“…Resistivity has an inverse relationship with rock porosity and clay content, degree of saturation and salinity of water (Mohamaden & Ehab, 2017). In the resistivity method, current is injected into the subsurface using a pair of electrodes while the potential difference is measured using another pair of electrodes placed in between the first pair (El-Sayed et al, 2023). For the ERT, Wenner array with electrode spacing of 10 meters was used and each electrode line was 300 meters.…”

“…Electrical resistivity method is increasingly being employed in groundwater exploration because of its simplicity in field application, varying adjustable depth of investigation giving useful information about layers being investigated including their level of saturation (El-Sayed et al, 2023), availability of robust 1D, 2D, and 3D interpretation software (Wahab et al, 2021). It has wide application in hydrogeological studies which include estimation of aquifer depth and thickness, detecting contaminant plume, determination of aquifer hydraulic properties, aquifer recharge monitoring and characterization of saline intrusion in coastal aquifers (Wahab et al, 2021) and has been used successfully in various groundwater exploration campaign (El-Sayed et al, 2023;Wahab et al, 2021).…”

Electrical resistivity investigation was conducted using the Wenner-α and Schlumberger configuration around the Edati hill of the northern Bida Basin to understand the groundwater potential and electrical characteristics of the subsurface lithology. Eight electrical resistivity tomography (ERT) lines and thirty-one electrical resistivity sounding (VES) points were occupied in the study. The ERT inversion results revealed two to three layers within the studied depth, as follows; (a) a clayey to silty layer with varying resistivity (49.1Ωm to 11035Ωm) and thickness, representing the top soil; (b) a very thick claystone layer with resistivity between 383 Ωm and 3261 Ωm, corresponding to non-porous, non-aquiferous ferruginized claystone and sandstone layer, except in the northwest where the sand is non-ferruginized and aquiferous; (c) an intermediate to high resistivity (104 Ωm to 5999 Ωm) layer which forms the main aquifer in the northwest with thickness between 15 and 40 meters. The result of the VES revealed four to five geoelectrical layers; a variable resistivity dry surface layer; increasingly high resistivity second to fifth ferruginized clay layer, with very thin aquifer at depth beyond 150 meters. The second and third layers in the northwest are low resistivity aquiferous sandstones. Sustainable borehole drilling has been determined to be in the northwest of the study area at depth of 70 meters.

The southern Mediterranean coast suffers from limited water resources as a result of exploitation of water supply, population growth, and climate change. Spatial lineaments and Seawater Intrusion (SWI) were detected at the southeast portion of Ras El Dabaa, on Egypt’s northwest coast, using the direct current resistivity (DCR) method. The Vertical Electrical Sounding (VES) data were acquired using Schlumberger array along four profiles and inverted both independently and jointly, aiming to obtain Two Dimensional (2D) geoelectrical images. The results of the one Dimensional (1D) inversion of VES data at each profile were stitched to form pseudo-2D sections on which the resistivity values and aquifer thickness in the southwest of the region appeared to be generally increasing, indicating a potential improvement in water quality.However, the results did not fully image the lateral variation but focused on the horizontal boundaries of the subsurface. On the contrary, the results of 2D inversion of the same data sets successfully managed to provide images that depicted resistivity distribution in both lateral and vertical directions. The detected sets of lineaments and fractured zones within the oolitic limestone and fossiliferous limestone units control the occurrence of groundwater in the region. The 2D inversion scheme revealed a low resistivity zone that indicated the presence of SWI and/or the dissolution of marine salts from the marine limestone bedrock of these aquifers in the northern portions of the studied area. Additionally, analysis of the 2D apparent porosity section shows how aquifers are connected by secondary porosity, which is defined by structures that resemble channels. The current approach offers valuable structural information for future planning and development of such complex geological coastal locations, taking into consideration the vulnerability of the groundwater system.
