Utility of forward and inverse modeling in 2D electric tomography for Hydrogeologic studies

Abstract The choice of adequate techniques and arrays in electric tomography prospection is a difficult task; it depends generally on subsurface geology and the referred objective, this study is conducted in southern Algerian Sahara aquifer using 2D electric tomography techniques, the goal is testing different arrays configuration, using 2D model simulating the subsurface geology, the validated parameters from the theoretical study are applied to the real data, the results attest the usefulness of synthetic modeling choosing the correct parameters in geophysical prospection.
