Aims: This research was carried out to determine: the variation in resistivity of the different soil profiles in the area, the depth and thickness of the weathered basement, the depth and thickness of the aquifer, the depth to basement, and to establish areas suitable for borehole development. Materials and Methods: Vertical Electrical Sounding (VES) was carried out using Schlumberger electrode array. A pair of potential and current electrodes was arranged in such a way that the potential electrodes were positioned in between the current electrodes and the positioning of the electrodes was set out using the measuring tape. The Ohmega resistivity meter was used for the data collection which measures the apparent resistivity of the subsurface. Results and Conclusions: The results showed that the area is composed of four (4) to five (5) layers, namely; the topsoil, clay, sandy clay/clayey sand, sand, and dry sand. The top soil has apparent resistivity ranging from 134.2 to 790.9 \(\Omega\)m with thickness and depth between 0.4 and 2.4 m. Clay is found mainly in traverses 1, 7, and 8. It has apparent resistivity ranging from 37 to 77.4 \(\Omega\)m , thickness between 2.9 and 1.9 m and depth within 5.0 and 16.9 m. Sandy clay/ clayey sand are concentrated in traverses 1, 3, 5 and 8 with apparent resistivity range between 18.4 and151.8 \(\Omega\)m ; thickness of about 1.3 to 18.8 m , and depth ranging from 2.3 to 35.7 m. The sand has apparent resistivities of about 226.2 to 610.8; thickness between 0.4 and 7.7 m, and depth ranging from 1.0 to 12.2 m. They are found in traverses 2, 3, and 4. Dry sand/ dry sand (with quartzite) have apparent resistivities ranging from 407.8 to 924.3 \(\Omega\)m . It has thickness ranging from 0.8 to 3.2 m and depth between 0.8 and 5.1 m. Perched aquifer could be found in sand and sandy clay. Wet sand contains both confined and unconfined aquifers while clayey sand harbours confined aquifer.

“…Several researchers have used electrical resistivity method to delineate and evaluate aquifer properties in various locations around the world (Heigold et al, 1979;Niwas and de lima, 2003;Abiola et al, 2009;Daniel et al, 2015;Adeeko et al, 2017;Emmanuel et al 2021;Agada et al, 2021;Agada and Yakubu, 2022). Electrical resistivity method has proven to be a veritable tool for groundwater exploration over the years, and its efficiency depends on soil saturation, porosity, fluid dynamics, permeability, groundwater chemical composition and rock lithology.…”

In this study we estimated the aquifer hydraulic parameters of Damaturu, Yobe State, Nigeria, using electrical resistivity method. Schlumberger configuration was adopted for the study. Five geologic layers, which are the Topsoil, Clay, Sand, Sandy-clay, and Sand were delineated in the study area. The results of the measured aquifer parameters revealed that the aquifer resistivity values in the study area ranged from 126 to 518 Ωm and the aquifer has an average resistivity of 328 Ωm. The aquifer thickness ranged from 39 to 71m with an average value of 59 m. The aquifer has hydraulic conductivity values which ranged from 1.138 to 4.231 m/day with an average value of 1.915 m/day. The transmissivity of the aquifer ranged from 62.7 to194.64 m2 /day with an average transmissivity of 111 m2 /day. The porosity of the aquifer ranged from 30.13 to 31.44 % with an average value of 30.6 %. The porosity values showed that the study area has an appreciable porosity for effective groundwater flow and storage. The results of the measured aquifer parameters also revealed that the study area has good groundwater potential. Therefore, the results of this study will assist in providing exquisite information for groundwater exploration, abstraction, development and pollution control in the study area.
