In many cases, however, the subsurface cannot sensibly be re- solved into horizontal homogeneous layers or into simple zones with lateral conductivity variations as required for profile interpre- tation. In this study, two-dimensional (2D) electrical resistivity tomography (ERT) surveys were combined with VES surveys to as- sess groundwater potential and evaluate the shallow subsurface of the basaltic greenstone formation of the Matsheumhlope well field aquifer in Bulawayo, Zimbabwe.
