The M’rara region belongs to the North-Eastern basin of the Algerian Sahara. Indeed, this area is the locus of two major aquifer systems. The main objective of this research was to obtain a two-dimensional (2D) resistivity model of the structures, based on the 2D inversion method that was performed by means of the algorithm Occam for 08 sites. The resistivity and phase data for both TE and TM modes, in addition to the tipper data, were jointly inverted. Additionally, the dimensionality of the data was analyzed by the phase tensor method, which allows us to obtain the 2D dimensionality below the period of 0.5 s. The resulting model of the 2D inversion was successfully used to identify the two aquifer systems; it also reveals the two horizontal superficial layers which are conductive and resistive, respectively.
