RELIABILITY ANALYSIS OF COASTAL RUBBLE MOUND STRUCTURES
For the last 20 years, the U.S. has averaged nearly one catastrophic tropical cyclone per year. This chronic coastal storm risk has provided impetus for the Corps to quantify the coastal storm hazard with improved analytical and statistical accuracy. These cyclones damage and weaken infrastructure, such as more than 1,000 coastal rubble mound structures in the Corps’ vast infrastructure portfolio. In 2019, Corps’ engineering and design efforts included billions of dollars of new or modified structures; however, existing guidance is outdated. The Coastal Hazards System (CHS) and StormSim are two research products that provide tools and data to compute accurate, risk-informed reliability for coastal rubble mound structures. CHS is a national probabilistic coastal storm hazard resource that accurately quantifies detailed and comprehensive storm hazards on a national scale. StormSim is a suite of stochastic analysis and probabilistic modeling tools for coastal engineering that applies CHS modeling suites. Together, these research products save time and costs associated with local and regional studies, facilitating more efficient rubble mound structure design and quantification of risk.
