geophysical methods

Two numerical simulations using Feflow® software were conducted to demonstrate the utility of geophysical data to accurately determine groundwater levels and provide additional data to the groundwater modelling community to improve the model’s accuracy. One simulation is based on regional piezometric data, and the other uses geophysical data acquired through transient electromagnetic (TEM), electrical resistivity (ERT), and ground-penetrating radar (GPR) surveys.

Acid-mine drainage

This paper describes the results of geohydrological studies conducted at Matsopa Mine, where a shallow bentonite body is mined, to investigate the potential impacts of mining on the groundwater environment. An understanding of such potential impacts is crucial since the communitiesin the area are dependent solely on groundwater for their domestic water supply.

In this study the groundwater resource in the Tsineng area in the Northern Cape Province was assessed in terms of the volumes of water that may be sustainably removed from the aquifer system, and the quality of the available groundwater. A strong emphasis was placed on the use of airborne and ground geophysical techniques to gain a better understanding of the geological and geohydrological conditions in the study area.

The Council for Geoscience has a corporate responsibility in rural development projects as part of the South African government initiative in food and water security. Geophysical surveys were carried out at Elizabeth Conradie School in Kimberley, Northern Cape Province South Africa aimed on siting production boreholes to supply the school with water. Traditional geophysical techniques including magnetic, electromagnetic and resistivity were used to locate groundwater bearing structures.
