    The anomalies triggered by the diversified terrain can lead to a false interpretation of the field data, thus, it is extremely crucial to take into consideration the topography on the inversion level. The paper discusses some elements of the Electrical Resistivity Imaging, deformation of the DC electrical field as well as the changes of the array geometric factor that are caused by the presence of the varied topography. It was pointed out that those distortions can cause strong changes in the values of the measured apparent resistivities. With the aid of professional software, chosen situations showing that the landform features can point to the existence of false sub-surface structures or conceal the presence of the actual structures of diversified resistitive character were modeled. Moreover, the field study results were presented and the influence of topography on them was illustrated with the modeling.
