In order to delineate variations of the alluvial deposits thickness at the wadis sites the best geophysical techniques to be employed are the electrical or electromagnetic methods because of the electrical contrasts between conductive over-bank deposits and the resistive coarse-grained sediments in the inner wadis as well the contrast between the higher resistive basement rocks and the overlying saturated zone of weathered basement and the alluvial deposits which are overlain by more resistive dry superficial deposits.
