Geo-electrical investigations have been carried out along the Nossob River in the Kalahari Gemsbok National Park and in the Nwanedzi area of the Kruger National Park. The object of these investigations was to locate potable groundwater supplies with a greater degree of accuracy than the random drilling of boreholes was able to do. The successful completion of the investigations has proved that when correctly applied the geo-electrical technique is a valuable aid to locating favourable target zones for groundwater development, thus resulting in considerable economic benefits.
