“…The anisotropy of rocks can be caused by their fracturing or metamorphism, as well as the presence of disseminated ore grains. Lower values of λ are associated with high aquifer potential zones, according to recent studies by Venkateswara et al (2022), Suneetha et al (2021), andShailaja et al (2019).…”

This study aimed to explore groundwater potential zones in the EGMB of Alluri Seetharama Raju district, Andhra Pradesh, India, for drinking and agriculture purposes. To achieve this goal, 72 Vertical Electrical Soundings (VES) were conducted using the Schlumberger electrode configuration. The resistivity sounding data were analyzed to determine the aquifer thickness, basement depth, Dar-Zarrouk parameters, and aquifer transmissivity. Spatial distribution maps were generated for these parameters to understand the subsurface formation. The analysis revealed a linear groundwater potential zone (8.46 km 2 ) in the eastern part of the study area, extending in the NNE-SSW direction for 9.6 km. Six VES locations (P24, P27, P29, P30, P33, and P38) in this zone exhibit good potential (>30 m aquifer thickness), while the three VES locations (OP19, P5, and P46) in the central region are recommended for drilling bore wells. Additionally, moderate aquifer thickness (20-30 m) are identified in other VES locations (OP14, OP20, P4, P10, P12, P13, P15, P17, P18, P31, P46, and P50) along streams in the western and central part of the area, which can yield reasonable quantities of water. This information is useful for groundwater exploration and watershed management to meet the demands of tribal population in the study area.

“…Levels of transverse resistance are typically associated with regions that are very transmissive and thus highly permeable to groundwater flow. This suggests that the research area's prospective aquifer regions expand as transverse resistance rises, which is likely the result of increases in hydraulic conductivities (Naidu et al 2021). Therefore, based on the values of the transverse resistance, it can be indicated that the northern part of the study area is highly productive compared to the southern parts.…”

“…Sankar et al (2022) and Alabi et al (2021) applied Dar Zarrouk parameters to predict the vulnerability of groundwater aquifers to surface and subsurface pollution. Naidu et al (2021) used longitudinal conductance and transverse resistance to delineate the interface between the fresh and saline water in coastal aquifers. However, the Dar Zarrouk modeling, like all geophysical approaches, is subjected to solution ambiguity.…”

The recent research is carried out to model the characteristics and productivity of the groundwater aquifer in the Omdurman area, Sudan, by combining electrical resistivity and pumping test methods. Omdurman is the most populous city known as the traditional capital of Sudan. Vertical electrical sounding (VES) survey using Schlumberger array is carried out along four profiles to delineate the potential groundwater zones. Application of 1D geophysical inversion revealed five geoelectric layers, including recent deposits, clay, silicified and ferruginous sandstone, and sandstone. Additionally, based on the outcome of VES inversion, Dar Zarrouk parameters, including transverse resistance and longitudinal conductance, were calculated to model the aquifer characteristics. The transverse resistance ranged from 5587 to 309,853 Ωm2, while the longitudinal conductance varied between 0.14 and 2.5 Ω−1. The hydraulic conductivity and transmissivity are further measured using the VES data, ranging from 1.4 to 5.2 m/d and 435 to 1564 m2/day, respectively. The step-drawdown pumping tests were performed to evaluate the aquifer characteristics and thus validate the result of the geoelectrical method. The transmissivity obtained from the step test varied between 583 and 1226 m2/day, showing an acceptable agreement with those of geoelectrical data. Based on the measured parameters, the aquifer is classified as highly productive and ideal for groundwater development. The step drawdown test was further used to assess the performance of groundwater wells. The results indicated that faulty well design and inappropriate pumping rates influence some wells in the study area, resulting in high drawdown and low well efficiency. Overall, the objectives of the study were successfully achieved; nonetheless, detailed hydrogeological and geophysical investigations are recommended for comprehensive evaluation of the groundwater aquifer.

“…Today's geophysical designs are able to deliver more significant information about the geology of the subsurface. There is a relationship between geoelectric methods, aquifer hydraulic features, and geophysics variables (hydraulic resistance and transmissivity), particularly lateral conductivity and lateral resistivity [9,12]. This relationship exists because geoelectric methods measure aquifer hydraulic features.…”

Concerns have been raised over the availability of water in the Dendam Lake neighborhood of Bengkulu City and the areas surrounding it. The location is characterized by a number of unsuccessful water wells. These issues are the direct and indirect results of the geological formations that are present in the region, specifically Aluvium (which consists of boulders, clasts, sand, silt, mud, and clay). A MAE X-612 EM resistivity meter was utilized in order to get a total of twenty Vertical Electric Sounding (VES) measurement points. Using the software programs Progress and Surfer, the data that was gathered was plotted on a two-log graph. The geoelectric layer and layer parameter maps that were made were prepared with the use of quantitative and qualitative interpretations. It was determined that there were between three and five geoelectric layers. It has been demonstrated that the resistivity of the subsurface shallow groundwater zone ranges from 10 to 20 Ωm at a depth of 4 to 15 meters. According to the findings of this research project, employing the VES geo-electrical exploration approach is likely capable of effectively outlining the subsurface and shallow groundwater. In addition, there is no information available regarding the precise depth of the groundwater table in the region. On the other hand, the underground groundwater at this location has a depth that is shallower than the norm.
