澳大利亚福斯河开发梯级由塞沙那坝(110m)、迪维尔斯盖特坝(DevilsGate)(84m)和佩卢纳坝(Paloona)(43m)3座大坝组成,建于1964～1971年。一旦大坝失事,对下游人口有重大威胁。根据采用1990年开发的综合方法对澳大利亚东南部极端降雨的评估结果,这3座大坝的溢洪道已不符合现行标准。溢洪道改造项目已于1999获得批准,计划于2003年施工完成。介绍了风险决策的过程。 The Flowserve River development cascade in Australia consists of 3 dams of Cezanne (110m), DevilsGate (84m) and Paloona (43m) built between 1964 and 1971 . Once the dam crashes, there is a serious threat to the downstream population. Based on the assessment of extreme rainfall in south-eastern Australia using a comprehensive methodology developed in 1990, the spillway of the three dams has fallen short of the current standards. The spillway reconstruction project was approved in 1999 and construction is scheduled to be completed in 2003. Introduced the process of risk decision-making.
