Risk-Informed Decision Making: Chapter 4 - Risk Management

Risk Informed Decision-Making (RIDM) is a method of dam safety evaluation that uses the likelihood of loading, dam fragility, and consequences of failure to estimate risk. This risk estimate is used along with standards- based analyses to decide if dam safety investments are justified or warranted. This approach has many benefits including a greatly improved understanding of the safety of the dam and identifying dam safety vulnerabilities that have not been identified using standards-based evaluation techniques.
Chapter 4 provides a discussion on risk management, including prioritization and urgency of dam safety actions and risk communication.
