Modeling Wind Wave Evolution from Deep to Shallow Water
Abstract
Ocean waves are an important aspect of upper ocean dynamics, in particular on shallow continental shelves and in coastal areas. The long-term objective of this work is to advance modeling capability in such coastal areas by improving model representations of effects associated with nonlinearity, medium variations, and dissipation. The specific objectives of the present work are 1) to develop and implement an efficient and scalable approximation for the nonlinear quadruplet source term, 2) to develop a generalized nonlinear source term that is accurate in water of arbitrary depth, 3) to develop improved nonlinear closure approximation for triad nonlinear interactions in shallow water, 4) to develop and implement a new stochastic model for coherent wave interference induced by varying depth and currents, and 5) improve representations of dissipation by wave breaking and wave-bottom interactions in shoaling waves.
