Geophysical Survey for Groundwater Resource Appraissal in a Basement Complex Terrain for Agricultural Purposes;Case Study of ABUAD Teaching and Research Farm, Ado Ekiti, Southwest Nigeria
aquifer, VLF-EM, vertical electrical sounding
Abstract
A combined geophysical survey involving the Very Low Frequency Electromagnetic and the Electrical resistivity survey has been carried out in the Teaching and Research Farm of the Afe Babalola University along Ado -Ikare road, Ado Ekiti with a view to determining the subsurface layers and thickness of the overburden as a means to appraising the ground water potential in the study area. Seventeen (17) west east traverses were established from which VLF -Electromagnetic data were acquired at a station interval of 5m each, the modeling and interpretation results from these were used to delimit the farm area into a total of 29 points from where vertical electrical soundings were carried out for further detailed survey using the Schlumberger electrode array configuration. The sounding data was processed and interpreted using WINRESIST interpretation software.
