Geoelectrical Investigation of Groundwater Potential, at Bosso Campus, Minna, Niger State, Nigeria

摘要

Geoelectrical investigation of groundwater potential has been carried out at Bosso Staff Quarters Bosso campus, Federal university of Technology, Minna. The area is situated on latitude 9°38＇55.8"N and 9°39＇29.0"N and longitude 6°31＇19.7"E and 6°31＇46.7"E. the survey was carried out with the aim of delineating the potential area for groundwater development and depth to the groundwater within the study area. The Schlumbeger array was used to sound six profiles with a total of 36 Vertical Electrical Sounding (VES) points. The sounding interpretation results were used to generate geoelectric section. The corresponding geologic section were also generated which revealed the existence of three subsurface layers. These layers revealed the existence of three subsurface layers. These layers comprise the top soil, weathered/fractured basement and fresh basement. The results of this analysis are presented as curves of apparent resistivity versus depth, from the digitalized curves obtained from the IP2WIN software, sulfur 11 was used to generates iso-resistivity map at different depth. The analysis of results shows that the area is not appropriate for borehole drilling.
