Introduction behaviour of non-temperate water systems in a large semi-arid region of Earth. Its publication at this time provides a synthesis of knowledge about such limnological systems, and in so doing offers support for the recent views of W.D. Williams (1988) in his opinion paper in Freshwater Biology on th

The geomorphology of southern Africa and subsequent coastal abrasion. This coupled with the major tectonic uplift of the Drakensberg to the east, the Cape fold mountains in the south and the Namibian massif in the west all combined to define the pattern of river drainage in the subcontinent.

Types of rivers and their characteristics-limited South, of which the western side is truly arid, and the eastern and southern regions are more adequately provided for.
