Application of the multi-electrode resistivity method to surface-water/ground-water interaction as applied to vegetation controls

The South African National Water Act of 1998 makes provision to have a groundwater reserve set aside to cater for<br>basic needs and ecologic use of water. Groundwater/surface water interaction is of import to define this groundwater<br>reserve. The distribution of vegetation around the Langebaan Lagoon is expected to be at least in part dependant on<br>groundwater conditions.
