Abstract

The main purpose of this study was to compare hydrogeological and electrical properties of a consolidated sandstone aquifer. Transmissivity and hydraulic conductivity of the aquifer were determined at fourteen sites from controlled pumping and recovery well tests in Gedaref area, Eastern Sudan. Aquifer electrical resistivity, corrected transverse resistance and apparent formation factor were obtained from vertical electrical sounding measurements carried out at the same sites of the aquifer tests. Results of the study show a linear direct correlation between the transmissivity and the corrected transverse resistance. An indirect linear correlation was observed between hydraulic conductivity and apparent formation factor. The methodology adopted for this study can be applied to different areas but not the empirical relationships,
