Abstract

The paper discusses the initial stages and development of a method of risk-based dam safety evaluation for the Department of Water Affairs. The analysis methodology used by the Department is discussed briefly. The method; of calculation used to determine probabilities of failure and the way in which dambreak analyses are done are summarized. Guidelines that should be used by the decision-maker as regards factors such as the acceptability or otherwise of levels of threat and risk of dams are examined next, followed by a few conclusions and recommendations.

In hierdie referaat word die aanloop tot en die ontwikkeling van 'n risikogebaseerdedamveilligheids-evaluasiemetode vir die Departement van Waterwese bespreek. Vewolgens word die ontledingsmetodologie wat in die Departement; gevolg word, kortliks bespreek. Dieberekeningsmetodes wat gevolg word om waarskynlikhede van swigting te bereken en die wyse waarop dambreekontledings gedoen word, word slegs opsommend weergegee. Hierna kom hulpmiddels wat die besluitnemer moet lei met aspekte soos die aanvaarbaarheid al dan nie van bedreigings- en risiko-vlakke van damme onder bespreking, waarna enkele gevolgtrekkings en aanbevelings volg.
