Synopsis provided by author:
The dissertation gives a description of the topography and meteorology of the Windhoek region. Existing water resources are described. Efforts made to synthesize records of past run-off from rainfall, having regard to recent records of rainfall and run-off, are discussed. It is concluded that variation in rainfall intensity and a sparsenes of rainfall stations render it impossible to derive an expression connecting rainfall and run-off for both drought and normal rainfall seasons. Instead reliance is placed on relationships derived from curves of massed run-off and rainfall in order to synthesize past records of run-off. Account is taken of historical information on droughts and when run-off of the two major rivers reached the sea
Expressions are derived connecting meteorological data and gross [word illegible] evaporation and reservoir co-efficients are suggested. Silting of reservoirs is discussed
Storage/draft relationships for four reservoirs are analysed. The total supply from the reservoirs together with water reclaimed from sewage plus the run-off (which should be stored underground) of three endoreic rivers is estimated. It is concluded that water will have to be imported into the region during the 1990s
