Abstract

The nature of risk analysis as applied to earthfill dams for the purpose of safety assessment is examined with particular reference to the matter of demonstrating the scientific validity of risk constructs used to inform important dam safety decisions. The qualities and attributes of what would be considered to be transparent, credible and defensible risk analyses for dam safety decision-making are outlined. A conceptual approach to addressing the problem of quantifying internal erosion risk that combines critical state soil mechanics theory and dynamic event tree analysis is proposed. Finally, an experiment aimed at assessing contemporary capability to detect the “changes of state” is described.

Risk Analysis in Geotechnical and Earthquake Engineering: State-Of-The-Art and Practice for Embankment Dams

Arlington, Virginia

The nature of risk analysis as applied to earthfill dams for the purpose of safety assessment is examined with particular reference to the matter of demonstrating the scientific validity of risk constructs used to inform important dam safety decisions. The qualities and attributes of what would be considered to be transparent, credible and defensible risk analyses for dam safety decision-making are outlined. A conceptual approach to addressing the problem of quantifying internal erosion risk that combines critical state soil mechanics theory and dynamic event tree analysis is proposed. Finally, an experiment aimed at assessing contemporary capability to detect the “changes of state” is described.
