Geoelectric measurements for groundwater assessment in Gedaref Area, Sudan

Abstract EN

-Vertical electrical soundings (VES) and hydrogeological data from Gedaref area of Sudan were collected, analysed and interpreted to test the possibilities and limitations of VES in groundwater exploration and evaluation .

The resulls which were presented in the form of resistivity , salinity and transverse resistance (T) maps had shown a close agreement with the general hydrogeological condition of the region .

Zones with maximum (T) are usually good targets for drilling fresh water wells.

Correlations had also been made between aquifer resistivity and water salinity .

The correlation procedure adopted in this study could be applied 10 evaluate water pros pects of new target areas in the region or elsewhere.
