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.

The climatery readable text describing the atmosphere and weather of southern Africa. These excellent reviews of the vagaries of the subcontinent’s climate stress the overall aridity of the area which increases from east to west.

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. Fig. 3.3 in Chapter 3 summarizes the rainfall of the region. The discrepancy in water resources between the north and south of the region is best illustrated by the mean an

In the southern African region, the Zambezi, the Okavango and the Orange Rivers certainly fall into this category, and are described individually in this chap

A review of river research in southern Africa since 1900 rather to describe the progression towards an understanding of the ecology of our rivers.
