Quantitative Risk-Informed Design of Levees
The U.S. Army Corps of Engineers (USACE) has been conducting economic risk analyses for evaluating benefit cost ratios for levee projects since the 1960s. With a new focus on life safety, these same analytical techniques are now being used to evaluate priorities for infrastructure investments and required design reliability to achieve various goals, including both national economic development and life safety risk reduction. Using an actual but unidentified levee project, this paper will demonstrate how the USACE is integrating traditional probabilistic levee fragility assessments, as described in the USACE engineering technical letter (ETL) 1110-2-556, with event-tree based system-response and fragility curve development processes described in the joint publication between the United States Bureau of Reclamation (Reclamation) and USACE entitled Best Practices in Dam and Levee Risk Analysis (2015). Using these methods, risk-informed levee designs for construction of new and remediation of existing levees can be developed and prioritized for action and investment.
