Electrical resistivity topography methods have been widely used to determine the thickness and resistivity of stratified media in order to assess groundwater potential and locate perforations in fractured unconfined aquifers. Traditionally, this has been done using one-dimensional (1D) vertical electric survey surveys. However, 1D VES surveys only model structures in subsoil layers and do not provide complete information to interpret the structure and extent of subsoil hydrogeological characteristics. As such, the incorporation of two-dimensional (2D) geophysical techniques for groundwater prospecting has often been used to provide a more detailed interpretation of subsoil hydrogeological characteristics, from which potential sites for successful location are identified from the well. In this study, 2D electrical resistivity tomography was combined with 1D VES to produce a subsurface resistivity model to evaluate the availability of groundwater in the basaltic green stone formation of the Matsheumhlope well field in Bulawayo, Zimbabwe. Low resistivity (<50 Ωm) readings towards the central region of the study area suggest a high groundwater potential, while high resistivities (> 500 Ωm) around the western margin of the study area suggest a low groundwater potential . 2D electrical resistivity surveys provide a more detailed subsurface structure and can help identify the configuration of possible fractures that could lead groundwater to the surface subsoil of the study area. It is concluded that 2D electrical resistivity methods are an effective tool to evaluate the availability of groundwater in highly resisted and fractured basalt stone rocks. The methods provided a more accurate hydrogeophysical model for the study area compared to traditional VES. The results of this study are useful for the technical management of groundwater as they clearly identified suitable drilling sites for long-term groundwater prospecting.
