Abstract

Vertical electrical soundings (VES) were carried out in order to determine the groundwater potential of the Enugu State University of Science and Technology, Agbani, Nigeria. The instrument used was the ABEM Terrameter SAS 300B, employing the Schlumberger electrode configuration. Interpretation of the VES data by partial curve matching technique aided by computer modeling showed that the sampled earth subsurface can be described mainly in terms of four geoelectric layers. Estimate of aquifer characteristics showed that the thickness is highly variable and ranges from 20 to 45 m while the transmissivity ranges from 7 to 16.5  QUOTE  /day. Fine-medium-coarse grained sands constitute the aquifer in the area. The inferred transmissivity of the aquiferous layer enabled the delineation of the best portion of the study area for groundwater development programme.

 

Key words: Groundwater, aquifer, thickness, transmissivity, resistivity.
