Oceanographic Factors and Erosion of the Outer Banks During Hurricane Isabel

Abstract

The meteorological and oceanographic processes responsible for erosion of the Outer Banks of North Carolina during Hurricane Isabel have been simulated using a suite of numerical models. The computed wind, wave, current, and water level fields are used to drive a three- dimensional numerical sedimentation model that calculates nearshore sediment transport and erosion potential. The erosion potential is the quantity of sand that can be transported by the coastal transport system, which is the maximum volume that can be eroded. The potential erosion of the dunes is discussed by comparing the erosion potential to dune-beach volumes, which are not known in this study.
