Study of aquifer characteristics in northern Paiko, Niger State, Nigeria, using geoelectric resistivity method

Abstract

Vertical electrical soundings technique was used to evaluate the aquifer characteristics and distribution in the northern part of Paiko in Nigeria. A total of thirty vertical electricalsoundingswerecarriedoutusingABEMSAS4000 Terrameter, and the data was analyzed both manually and with software (Resist software). The result revealed the aquifer resistivity and thickness to vary from 10.9 to 80,368 Xm, and 1.06 to 72 m, respectively. Also, hydraulic conductivity rangesfrom0.010267to41.61928 m/day while transmissivity values range from 0.035215 to 70.09302 m2. The hydrogeological maps (hydraulic conductivity and transmissivity image maps) showed the variations of these parameters in the study area and that the southwestern part of the area has prolific aquifer
