Current State-of-Practice in Dam Safety Risk Assessment

Dams provide significant benefits to the nation, serving as critical infrastructure to deliver water retention and control throughout the United States (US). Major cities could not function without the fresh water supply stored in dammed reservoirs, and many electrical systems rely on dependable hydroelectric power supply. Dams on rivers across the country protect communities against destructive flood impacts while providing navigable waters for transportation, irrigation for agriculture, and various opportunities for recreation. While dams provide many essential services, dam failure flooding can present significant risks to property and life. Over decades of experience, dam safety practices, including risk assessment, have evolved as engineering knowledge, scientific understanding, and technological advancements grow. This project summarizes the current state-of-practice in dam safety risk assessment.
