Description :
South Africa is already hydrologically vulnerable and this is likely to be exacerbated by both nonpermanent ENSO-related as well as more permanently greenhouse-gas forced climate changes. Climate change effects are explained by way of the hydrological equation. This serves as a backdrop to a brief review, in a hydrological context, of projected pertubations to temperature, rainfall and potential evaporation, over southern Africa. These include the application of appropriate hydrological models for use in impact studies. Scale problems of importance to hydrologists are highlighted.
