ABSTRACT
This research study used a vertical electrical sounding approach to investigate the transmissibility size of the hydrogeologic units under inquiry. This was brought on by failed water scheme initiatives and rapid population growth. Aquifer resistivity and thickness values were utilized to generate the hydraulic parameters that were used to describe the transmissibility magnitude.The Schlumberger design was used to conduct 16 VES surveys for the investigation, with a maximum electrode spacing of 200 m. The Dar-Zarrouk parameters longitudinal conductance (S), transverse resistance (T), longitudinal resistance (L), average transverse resistance (t), coefficient of anisotropy (λa), transmissivity (T), and hydraulic conductivity (H) were used to evaluate the aquifer’s protective capability. Results from VES data indicated that the layer model ranges from three to six layers, and it was found that curve A was the most common type of curve. Results from the study revealed that S, Tr, ρL, ρt, λa, T, and H ranges from 0.02 to 0.18 Ω−1 , 761.7 to 31336.1 Ω /m2, 287.8 to 12314.4, 101.7 to 767.7, 0.15 to 0.69, 0.000003 at VES/12 to 0.0538 m/day, and 0.05 to 65.56 m2/day respectively. Deduction from the study revealed that northwest, and northeast parts of the study area tends to be more aquiferous when compared to other parts of the study area.
