Abstract :

Geo-electrical survey involving vertical electrical sounding (VES) was carried out using Schlumberger electrode configuration. The study aimed at estimating the aquifer hydraulic parameters in parts of Batagarawa area, Katsina state. Twenty four (24) VES were carried out. The interpreted and analyzed results reveal three to five geo-electric layers. The aquifer resistivity range from 0.274 to 2580 Ώm while aquifer thickness ranges between 1.25 to 29.5m. The transverse resistance ranges between 0 and 16583 Ώm2. The range of hydraulic conductivity is 0.254– 1292.767 m/day, while the range of transmissivity is 0– 38,136.627 m2/day from the estimated values. The contour maps were drawn using the electrical and hydraulic parameters, and the distribution of the aquifer hydraulic parameters was shown. Low spatial variability of hydraulic conductivity suggests strong homogeneity of the aquifer system. Based on the results, the assessment indicates that there is low groundwater potential in the greater part of the study area particularly western, eastern and slight northern part. Keywords: Aquifer properties; basement terrain; geo-electrical method; hydraulic characteristics.
