Modeling of Finite Depth Wind Wave Dissipation

The objectives are to establish a description of the “white-capping” dissipation both as a spectral function and a function of environmental conditions. To date, knowledge of the spectral distribution of energy losses due to wave breaking is so poor that scientific debate continues on whether, in the spectral sense, low-frequency dissipation exists or not. Also there is little knowledge of the dependence of the dissipation rate function on wind and wave field characteristics, other hydrodynamic properties and interaction with the bottom. All of these factors make dissipation rate functions used in present day wave models, to a large extent, speculative.
