Abstract:

Three numerical hydrodynamic models with progressively finer grid resolutions, utilizing the finite difference code WIFM, were developed for the purpose of evaluating the influence of proposed structures under storm conditions and providing elevation and velocity data for concurrent numerical sediment transport studies at Oregon Inlet, North Carolina. The offshore model encompassed the entire Carolina coast over the continental shelf and was used to propagate storm effects from deep water to the finer resolution models. The nearshore model extended from Cape Henry to Cape Lookout, and provided finer detail along the Outer Banks, within Pamlico and Albermarle Sounds, and at Oregon Inlet. This model was used both tide and surge simulations and was the primary tool for establishing structural effects under storm conditions in the Oregon Inlet vicinity. It also was used to provide boundary conditions for the most detailed model of the study known as the shore process model. The shore process model encompassed less than 85 square miles centered about Oregon Inlet and provided high resolution at the inlet and in the surf zone. It provided more realistic circulation patterns of the inlet, the effects of jetties on inlet flow, and hydrodynamic data for concurrent numerical sediment transport studies.
