Direct Simulations of Nonlinear Three-Dimensional Wave and Wave-Group Dynamics

Abstract

LONG-TERM GOAL. The ultimate goal is to develop and apply effective and robust computational tools for nonlinear dynamics of three-dimensional waves and wave groups. Of immediate interests are the spatial/temporal coherence of such waves and the nonlinear mechanism of such coherent structures. This work is the first step of a long-term effort to obtain robust realistic simulations of nonlinear wavefield evolution including wind, current, and shallow water (bottom variation) effects. OBJECTIVES: To develop and improve efficiency and robustness of the high-order spectral (HOS) method for longtime/ large-space simulations of nonlinear wave-field evolutions. To develop methodologies for data assimilation and forecasting of nonlinear wave-field evolution dynamics. To study the coherence of three-dimensional steep waves and the mechanism for the development of such coherence structures and properties.
