Abstract

This study aims to incorporate the analysis and interpretation of aeromagnetic data with the results of vertical electrical sounding to investigate the horizontal and vertical extensions of subsurface contaminant plume caused by the wastewater dumpsite at the downstream of Wadi Uranah. It is also the aim of this study to investigate the subsurface geological and structural elements controlling the flow and accumulation of contamination. The results show that the contamination flow and accumulation are controlled mainly by the subsurface faults and basement topography. Subsurface faults form pathways for the contamination, while subsided basement blocks form basins with thick sedimentary cover, suitable for accumulation of the contamination. The southwestern part of the area, close to the Red Sea, is probably affected by seawater intrusion.
