The present study involves the use of vertical electrical sounding to understand the hydrogeological condition of the study area [10,11]. This will involve the determination of the thickness and resistivity of the subsurface layers, delineating the fracture zones, and establishing the depth of the bedrock, which will be done by governments, people, and non-governmental organizations to understand the features and nature of the aquifer in the area.…”

An electrical resistivity survey was conducted at different locations within Ayede Ekiti, Ekiti State, Southwestern Nigeria. This is aimed at evaluating groundwater potential zones and aquifer properties within the study area. Data were acquired at four (4) different locations using the vertical electrical sounding method by employing the Schlumberger array configuration. This study utilizes resistivity data processed with IPI2win software to analyze the subsurface geology of a basement complex region. The result of the study showed that qualitatively, three major curve types (A, HA, and H) were observed. Varying curve types, predominantly A curves, were observed across the research area, with notable groundwater potential indicated by H and HA curve types at select points. Through curve matching techniques, three to four distinct geo-electric layers were identified, while the quantitative interpretation resulted in deducing layers with different resistivity and thickness values for each VES(s) of the study area. It was deduced that the VES 2 and 3 zones are connected to a high output of groundwater. However, VES 1 and 4 are characterized by low groundwater potential. This research contributes valuable insights for geological mapping and groundwater resource assessment in complex basement terrains of the study area.

“…8). In the study, it showed that 3.6% (VES 7) of the VES points has the good protective capacity, 14.3% (VES 2, 8, 26 and 27) possess moderate protective capacity, 35.7% (VES 1, 3, 6, 11, 12, 13, 18, 22, 23, and 24) have the weak protective capacity, and 46.4% (VES 4, 5, 9, 10, 14,15, 16,17,19,20,21,25 and 28) possess a poor protective capacity. Most of the VES points in the study area possess values of poor to moderate protective capacity, thus indicating that the aquifers are slightly protected.…”

This study is intended at depicting the aquifer plausible zones in Modomo/Kajola, Ile-Ife using Dar Zarrouk parameters. The study area is situated amid latitudes 830,00–830,500 mN and longitudes 663,500–664,000 mE, overlying pegmatite and granite gneiss in the basement complex terrain. Twenty-eight (28) Schlumberger-array vertical electric soundings (VES) were carried out within the study area with the help of Terrameter SAS 300C. The VES interpretation result reveals three to five geo-electric layers: topsoil, clay/sand/lateritic layer, weathered layer, fractured basement, and fresh basement. The geoelectric sections showed the main aquifers to be unconfined, semi-confined, and confined composed of sandy clay, clayey sand, and sand with different thicknesses (aquifer thickness varying from 3.3 m to 15.8 m with a mean value of 9.9 m). The aquifer hydraulic characteristics show that the longitudinal conductance (L) varies from 0.014 Ωm to 1.000 Ωm with a mean value of 0.132 Ωm, the transverse resistance (T), varies from 677.4 Ωm2 to 6465.7 Ωm2 with a mean value of 2291.2 Ωm2. The Hydraulic conductivity (K) values vary from 29.4 m/day to 126.9 m/day with a mean value of 50.5 m/day. The transmissivity (Tr) values attained at many layers vary from 418.7 m2 /day to 465.1 m2 /day, with a mean value of 449.4 m2 /day. The GSLI values vary from 2.25 to 4.25 with a mean value of 2.9. Three aquifer plausible zones were depicted involving sandy clay, clayey sand, and sand.

The primary goals of this research are to detect the spatial variation of the hydrogeological characteristics and evaluate the groundwater quality in the eastern Nile River, Khartoum state, Sudan, using geophysical and hydrochemical methods. Thirteen Vertical electrical soundings (VES), using Schlumberger configuration, were measured along three profiles to characterize the groundwater aquifer. VES findings denoted that the study area comprises two hydraulically connected aquifers. The upper aquifer of sand has an average thickness of 50 m, and the lower aquifer is composed of sandstone of a thickness of up to 300 m. The results of VES inversion were further used to measure aquifer characteristics, including transverse resistance, longitudinal conductance, hydraulic conductivity, and transmissivity. The detected average values of these parameters were 6690 Ωm2, 1.4 Ω−1, 264 m2/d and 4 m/day, respectively. In addition, regression analysis was performed to suggest local relationships for estimating aquifer characteristics within the study area. On the other hand, total longitudinal conductance was used to predict the protective strength of the hydrogeological columns, ranging from 1.7 to 5.8 Ω−1; as a result, the protective capacity of the aquifer ranged from good to very good, suggesting potable water quality. This result was subsequently confirmed by the groundwater quality index (GWQI) model. Eleven physiochemical parameters analyzed for nine boreholes were used in GWQI estimation to assess groundwater quality in the study area. The primary analysis of the hydrochemical parameters indicated that almost all parameters are below permissible limits prescribed by the World Health Organization (WHO). The computed GWQI varies between 34.8 and 148, and the majority of groundwater samples, precisely 55.5%, are good water types, while 22.2% of the samples are in an excellent quality state. This research concluded that the groundwater aquifer in the study area is ideal for groundwater exploitation. However, applying a detailed geophysical and hydrochemical survey is recommended to reduce the uncertainty of the resulting models.
