“…The green region with resistance values of 100-500 Ωm is interpreted as a sand layer. This result is supported by a prior study from Nazri et al (2012) which found that Bagan Serai is based on material that has low resistivity reaching a thickness of 120 m. From the result in Figure 3(b), the low resistivity values of 50-500 Ωm at a depth of 0-38 m indicate the presence of alluvium sediment in that area as recorded in available well lithology and supported by the studies from Nazri et al (2012), Riwayat (2018), andZawawi et al (2011) which discovered the underlying sand at a depth of about 18-39 m in Bukit Merah. The zone with resistivity values of 500-2000 Ωm at depth of 38-51 m is linked to the shale layer with referencing to the nearby well logs (Jasin & Harun, 2007;Ashraf et al, 2018).…”

The knowledge of lithological formation is important to determine the potential aquifer for water resources management. This study aims to delineate the lithological formation of Bukit Merah, Semanggol using geological data. The preparation of lithological formation in the study was based on several factors such as electrical resistivity survey data, available well lithologies, geological map, and geological-related studies in the study area. The Electrical Resistivity Tomography (ERT) profile produced from the resistivity survey was interpreted based on previous studies to determine the subsurface materials on the location. The estimation of soil lithology for the remaining wells was done to generate the overall subsoil pattern in the study area. A total of 15 types of soil were classified to represent the actual lithology in the study area. The simplification of the actual lithology was carried out based on rocks and soils group. The elevation of the ground surface and each soil layer were imported into Visual MODFLOW software, then the interpolation of elevation points was done. Two interpolators; Kriging and Natural Neighbouring were used to generate ground surface and model layers similar to the topography in the study area. As a result, it has been identified that the study areas consist of 4 main layers of lithological formation which are unconsolidated deposit, sedimentary, metamorphic, and granite. The upper layer is dominated by unconsolidated with a maximum thickness of about 150 m in the coastal area. Hence, it is concluded that the unconsolidated deposit layer in Bukit Merah is highly potential with groundwater resources in the alluvium aquifer at the upper layer which has the potential to be developed for purpose of irrigation in a paddy field in the Kerian area.

“…The measured chargeability is the discharged measure of polarization in the subsurface. Basically, it is related to the water content in the subsurface media and the minerals conductivity (Riwayat et al, 2018). Hence, the chargeability profile could be used to determine the characteristic of water either it has impurities or not.…”

2-D electrical resistivity has been a proper investigation survey for determination of subsurface geophysical in describing the complex features geology profile. In this study, an electrical resistivity survey was conducted at paddy cultivation area located in Melor, Kelantan, Malaysia. Since the end plot of paddy field experiences water scarcity especially during dry season, there is a need to find other alternative water source. The study was conducted on 1st and 2nd February 2020 to identify zone area of groundwater for Melor, Kelantan. Four resistivity lines using Induced Polarization (IP) and 2-D Electrical Resistivity Imaging Technique were conducted using a set of ABEM Terrameter SAS4000. Short resistivity survey was applied to gained detail of subsurface formation near the ground, while the longer resistivity survey was applied to obtain deeper subsurface delineation. Measured data obtained was analyzed using RES2DINV software and result of contrast resistivity values was used to determine the geological structures, while the chargeability values were analyzed accordingly to determine area of expected potential groundwater zone. Results from the resistivity profiles show a range values of 0 Ωm to 50,000 Ωm with total maximum acquired depth of 65.6 m below ground surface. The chargeability profiles show a range values of 0 msec to 500 msec, that shows potential of groundwater zone area lies at 0 to 4 msec. It was found that at a depth of 60 to 75 m, 30 m from center of Profile B was suitable for a production well which was expected to be a potential area for groundwater zone.

“…The resistivity parameters were obtained along predetermined profiles using the Wenner array, with 5 m spacing between 40 copper steel electrodes. The length of each profile along the predetermined line was 200 m. The choice of the Wenner configuration was because of its advantage to provide good vertical resolution and clear image for groundwater and sand-clay boundaries as horizontal structures [3]. The borehole logs with which the 2D images were constrained were obtained from Hydro-Skill engineering services limited around the area.…”

The need to address the acute water shortage problem within the Ahmadu Bello University Zaria Campus in Samaru necessitated this groundwater exploration project. 2D geoelectric imaging and vertical electrical sounding (VES) surveys were carried out to investigate the groundwater potential of the study area. The 2D geoelectric models and sounding curves obtained were correlated with existing borehole logs obtained from the area, hence validating the results from the 2D resistivity survey. Results from the surveys showed three-layer lithologies with varying thicknesses and resistivity values. The topsoil showed resistivity values of between 4 and 170 Ωm, characteristic of clayey sand and sandy materials. The second layer is characterized by resistivity values ranging between < 4 and 90.6 Ωm, coinciding with zones of the weathered basement. The third layer which has resistivity values ranging between 90 and 550 Ωm constitutes the basement rocks. The thicknesses of the weathered regoliths favourable for groundwater exploration vary from 13.4 m around the Amina Hall, 16.7 m northeast-southwest of Akenzua Hall, 21.2 m northwest-southeast of Akenzua Hall, 24.3 m around Alex Hall and 25.3 m around the Suleiman Hall. These very important parameters reveal the groundwater potential of the study area and therefore suggest that groundwater can be developed and harnessed for use by the University but with a greater yield around the Alex and Suleiman Halls. VES survey was integrated with the 2D resistivity survey to provide information that compliment results from the 2D resistivity survey. The sounding curves were A-Type and H-type curves exhibiting low resistivity values (5–24 Ωm) within the second layer.
