The dams and hydropower industry has a demand to characterize the risk associated with its operations, and in particular, the risk of dam failure. In current practice, the capability to reliably estimate risk remains very weak. The reasons are essentially all due to the fact that the existing capability to characterize dam risk is the "extreme event" philosophy of dam safety that prevailed in the 1970's and 1980's. In terms of this philosophy, there could be no consideration of combinations of lesser floods and earthquakes. Beyond these physical dam safety concerns, this traditional philosophy does not consider operator error or procedural failures in any way, nor does it embody any consideration of institutional failures or contributions to risk. In particular the problem of "uncommon combinations of problems that individually are not uncommon" is omitted completely.

大坝和水电行业需要描述与其运营相关的风险，特别是溃坝风险。在目前的实践中，可靠地估计风险的能力仍然非常薄弱。其原因基本上都是由于这样一个事实，即现有的能力，以大坝风险的特点是“极端事件”的大坝安全的哲学，在20世纪70年代和80年代盛行。根据这一理念，不可能考虑较小的洪水和地震的组合。除了这些大坝的物理安全问题，这种传统的哲学不考虑运营商的错误或程序失败，也没有体现任何考虑机构故障或风险的贡献。特别是“个别并不罕见的问题的罕见组合”的问题被完全省略。
