A HYBRID MODEL FOR NEARSHORE NONLINEAR WAVE EVOLUTION

Field and laboratory data show the presence of an equilibrium in the high frequencies of surf zone frequency spectra. In this region, dissipation of high frequency energy equilibrates with nonlinear interactions that transfer energy primarily from low frequencies to high frequencies. The nonlinear interactions that describe nearshore wave evolution increase model complexity, which results in an increase in computational expense. To reduce the computational burden of a nonlinear wave model, it is combined with a parameterization for surf zone wave spectra, and different implementations of the parameterizations are tested and the results show that the predicted spectra and Hrms compare well with data and the full model nonlinear parameters skewness and asymmetry are not accurately predicted. Several ideas for future improvements are suggested. 2007 World Scientific Publishing Co. Pte. Ltd.
