Abstract:
This study presents the results of a Vertical Electrical Sounding (VES) using the Schlumberger array method, conducted to investigate the subsurface layer parameters of a 500 x 500 m land area situated between latitude 09o32′21.4′′ N to 09o32′37.8′′ N and longitude 06o27′29.2′′ E to 06o27′45.5′′ E, at the northern part of Gidan Kwano Campus, Federal University of Technology, Minna, Niger State.
A total of 36 VES points were collected at 100 m intervals, with a maximum half intercurrent electrode spacing (ab/2) of 100 m. The analysis revealed the presence of three geoelectric layers beneath the study area. The top soil layer exhibited resistivity values ranging from 10.6 to 1679.8 Ωm, with depths and thicknesses ranging from 0.5 to 4.2 m. The weathered layer displayed resistivity values ranging from 4.8 to 61.5 Ωm, depths ranging from 2.7 to 23.0 m, and thicknesses ranging from 2.1 to 21.1 m. The fractured/fresh basement exhibited resistivity values ranging from 158.7 to 1421.5 Ωm, but its depth and thickness could not be precisely determined.
The VES stations were categorized based on their potential for aquifer use. Five VES stations (A5, B4, B5, C2, and F3) were identified as having significant aquifer potentials. The resistivity, depth, and thickness of these aquifers ranged from 24.2 to 34.4 Ωm, 9.2 to 23.0 m, and 8.0 to 21.2 m, respectively.
Additionally, five VES stations (A6, B1, B6, C5, and F1) were delineated as suitable for civil engineering works due to their shallow depth to the basement. These findings provide valuable information for the assessment and planning of subsurface activities in the study area.
