Abstract

This work reveals the modeling contribution to the techniques of investigations in the electrical resistivity area. Two campaigns of electric soundings (maximum length AB = 6000 m) were conducted in the Saharan region—Hassi R’mel (Algeria), to supply two new cities with drinking water. An analytical procedure, also known as inversion, was applied to the processing of the registered measurements. The results of this interpretation allowed to locate the porous and permeable formations likely to be aquifers. A simulation algorithm based on the finite difference method has been adapted for the direct calculation of the electrical resistivity data. The obtained models laid a more detailed description of the subsurface structure. So, based on these results adjusted with the help of drill logs of the region, it is believed that the best orientation for the exploitation of these waters in the first evaluated zone (Bellil) is in the Northeast part of the area under investigation, whereas in the second region (Bouzbier), the privileged areas are those located in the North-east and the South-east parts.
