Current concern with catastrophic dam failures focuses on the safety goals for designing new dams and on possible retrofit of existing dams. Billions of dollars are at stake and with the passage of time the risk of disaster increases. The main objective of this project is to bring modeling of low probability/high consequence event, risk analysis and management, and economic analysis into dam safety. The work will be divided into four tasks as follows: task 1) collect and review dam failure data; task 2) model the economic and social benefits of dam operation; task 3) examine the comparative risks and risk goals for dam safety; and task 4) develop an economic model that will consider risk management alternatives with emphasis on public perception and information, and will investigate cost/benefit analysis.

当前对灾难性大坝故障的关注集中在设计新水坝和现有大坝可能改造的安全目标上。 数十亿美元受到危险，随着时间的流逝，灾难的风险增加。 该项目的主要目的是将低概率/高后果事件，风险分析和管理以及经济分析的建模用于大坝安全。 工作将分为四个任务，如下所示：任务1）收集和查看大坝故障数据；任务2）建模大坝运营的经济和社会益处；任务3）检查大坝安全的比较风险和风险目标；任务4）开发一种经济模型，该模型将考虑风险管理替代方案，重点是公众的看法和信息，并将调查成本/收益分析。
