Erosion during Hurricane Isabel
Abstract
A better understanding of the complex interplay between ocean waves, water levels, and currents, and the movement of sediment in the dune-beach system will improve predictions of coastal environmental hazards, water-column optics, bar movement, and mine burial -- all of which have tactical implications. Historically, this interaction of different processes has been modeled by using simple parameterizations. In this study, we explicitly simulate the above processes through a suite of numerical models. We use a depiction of the landfall of Hurricane Isabel (2003) on the barrier islands of Cape Hatteras, North Carolina, to examine potential erosion that contributes to barrier island breaching and washover. This prototype for a rapidly relocatable nearshore sediment transport modeling system will take advantage of recent advances in Navy technology for global deep-ocean and coastal environmental modeling.
