Evaluation of Groundwater Potential Using Integrated Geophysical Data in Parts of Michael Okpara University of Agriculture, Umudike, Southern Nigeria

Abstract

This study was carried out to investigate the groundwater potential in Michael Okpara University of Agriculture, Umudike area of Abia State, Nigeria. A total of nine vertical electrical soundings were acquired and the results were correlated with records available from an existing well together with previous lithologic deductions. A range of 4 to 6 geoelectric layers was delineated in this study; though the fourth and fifth geoelectric layers were predominant. Results showed that the aquifer is located within the third layers for the 4-layered zone and the fifth and sixth layers for the other layered zones. The depth to the shallowest aquifer is about 30m at VES 4 with the aquifer resistivity of 13124Ωm and transmissivity of 258.6 m 2 /d. The area has huge groundwater potentials with the best prospects at VES 2 and less promising results at VES 5.
