Geophysical evaluation of geohydrokinetic properties of aquifer units in parts of Enugu state, Nigeria

Vertical electrical sounding employing Schlumberger electrode configuration was carried out in thirty locations across some parts of Enugu state, to investigate the hydrokinetic properties of hydrogeologic units of the study area. The result shows that resistivity and thickness of aquifer ranges fro...
