Title:The occurence and potencial beneficial use of water in South Africa
Author:Kriel, J.P.
Periodical:RSA 2000: gesprek met die toekoms
Geographic term:South Africa
water supply
Abstract:Not only is a large portion of South Africa relatively dry, but the rainfall and the resulting river flows are erratic with long periods of drought which substantially reduce the proportion of the total runoff which could be made available as a reliable source of water supply. Sections: 1) Water resources of South Africa (rainfall - evaporation - runoff - potential beneficial use of surface runoff - sediment load of rivers - qround water resources - total potential water supply). 2) water consumption. 3) Comparison of water resource potential with estimated demand. 4) Meeting essential water requirements from existing water resources (manpower - provision of funds - research - co-operation of the water consumers - provision of storage - promotion of efficient water use - protection of water quality - realistic pricing for water). 5) Unconventional water resource development (re-use of effluents - desalination - abstraction of water from the atmosphere - antarctic icebergs - importation of water).
