2-D data modelling by electrical resistivity tomography for complex subsurface geology (is it possible to improve electronic interpretation of resistivity measurements with multielectrode devices in undeterminated cases?)

In the last years, there has been a widespread increase in the use of 2-D electrical methods surveys especially due to the development of automatically multiplexed measuring systems which facilitate the acquisition of a large number of measurements. These methods are mainly used to map area with complex subsurface geology, to study aquifers, and to identify covered structures in archaeological study. For this reason the interpretation and consequently the inversion procedure of electric methods has to be accurate.
