Exploration for Groundwater Aquifers, using Vertical Electrical Sounding (VES) method, in Wad Hamid area – River Nile State, Sudan

Abstract

Geo-electrical measurements using the Vertical Electrical Sounding (VES) method was utilized in determining aquifer characteristics of Wad Hamid area. Three geologic units wererecognized in the area; Quaternary deposits, CretaceousSandstoneFormation and the Basement Complex rocks. 122 VES using the Schlumberger configuration were acquired for the study area. A maximum half electrode spacing of 900 m was utilized for data acquisition. All these soundings were processed using IX1Dsoftware. Geo-electric sections were constructedfrom which the aquiferous layers were delineated.Hydraulic parameters (hydraulic conductivity and transmissibility) were computed at the existing borehole and VES sites.
