The Study of the Spatial Coherence of Surface Waves by Nonlinear Green-Naghdi Model in Deep Water

Abstract

The goal is to identify the role of nonlinear wave interaction in the spatial coherence of ocean waves within the MOB Program of ONR. For this purpose, a numerical tool based on the Green-Naghdi model will be developed to simulate short-crested irregular waves in deep water. The objectives are to develop the higher-level Green-Naghdi model, to provide oceanographers/ocean engineers with a new numerical, nonlinear wave model, and to simulate efficiently the fully-nonlinear interaction in short-crested random ocean surface waves. Emphasis will be placed on the optimization between accuracy and computational effort by adjusting the "Level" of the model.
