HURRICANE WAVE AND STORM SURGE FORECASTING FOR THE CAROLINA COAST

CASEY DIETRICH, North Carolina State University

Abstract

This presentation focuses on the coupling of a nearshore wind-wave model (SWAN) with a coastal ocean circulation model (ADCIRC). These models use unstructured, finite-element meshes to describe the ocean, continental shelf, coastline, floodplains and channels over a range of spatial scales. The models have been applied to the design of levee protection systems for metropolitan New Orleans by the U.S. Army Corps of Engineers and the state and local agencies, and the development of flood risk assessment maps by FEMA for the Gulf and Atlantic coastlines. Recent work has focused on the forecasting of hurricane waves and surge in real-time, including during Hurricane Arthur (2014), and the communication of predictions to emergency managers.
