Abstract

The characterisation of drought is something which has caused much debate and investigation and is even in the nineties still a thorny problem. This article describes a method whereby drought in natural veld is characterised by using a soil water balance to build a "climatology" of soil water content. The real time situation is then compared to the "soil water climate" and described in terms of probabilities.
