On-Demand Webinar: Event Tree Principles and Applications for Dam Safety Risk Assessment
Association of State Dam Safety Officials, 2015
Event tree analysis is commonly used in dam safety risk analysis. Event trees are tools used to aid in understanding, analyzing, and communicating dam safety risks and for informing dam safety decisions. Like all other tools they are imperfect and their potential value depends on the skills of their user. Event trees can be used to obtain quantitative estimates of the probability of dam failure and its associated consequences. This can be done for an existing dam or for structural or to compare non-structural risk reduction alternatives. Event trees can also serve as qualitative or diagrammatic representations of failure modes and their consequences. This webinar will summarize the principles of event trees and their application in dam safety risk assessment. It will include discussion of the construction of event trees, the calculations associated with event tree analysis and various type of post processing such as tolerable risk evaluation, which is important in support of dam safety decisions.
