Challenges of Forecasting Coastal Flooding
Richard Luettich, Department of Marine Sciences and Environmental Sciences, University of North Carolina at Chapel Hill
The use of coupled, multi-physics, high-resolution computer models to predict storm surge and flooding for research (e.g., process-based modeling studies) and for operational use in risk assessment (e.g., to delineate coastal flood hazard zones) and the design of risk reduction strategies (e.g., New Orleans, New York City) has become more common place during the past 10 years. However, operational use of the same models for event-based forecasting involves additional challenges including addressing uncertainty in meteorological forcing, marshalling necessary computational resources and making results available to a spectrum of end users. I will present an overview of the ADCIRC coastal hazards modeling system and the progress we've made using this system for event-based forecasting.
