A Community Approach to Improved Prediction and Characterization of Coastal Storm Hazards

The authors discuss the value, illustrated through recent and ongoing project experiences and results, of using modeling, data analysis, and field measurements in a community approach to coastal storm hazard characterization (e.g. hurricane wave conditions and water levels). The Interagency Performance Evaluation Task Force's (IPET's) recent work, commissioned by the U.S. Army Corps of Engineers, is one example. In response to Hurricane Katrina, the IPET was tasked with obtaining southeastern Louisiana hurricane protection system performance data. Another example is that the Corps of Engineers is leading efforts for designing projects to greatly reduce coastal Louisiana and Mississippi flooding consequences and likelihood. Such work is closely coordinated with efforts to update flood insurance rate maps for the affected region by the Federal Emergency Management Agency. The authors discuss challenges in accurate wave and surge predictions, as well as lessons learned and findings. These include nearshore wave set-up and coupling into surge model treatment problems; shallow coastal area wind drag law specifications; and coastal and estuarine wind field inaccuracy. The authors discuss a new community-based research program of the Corps of Engineers addressing many of these issues, and select problem areas' early progress results. The authors present open-source community-based computer software development advantages for coastal storm surge and wave predictions, and current proprietary software over-reliance issues.
