A second-generation numerical wave model, WINDWAVE, has been developed for wave prediction in coastal regions. The modal is based on the numerical integration of the energy balance equation for waves in water of finite depth. Three Source terms are included in the physical representations of the model. These terms describe wave growth due to the wind, nonlinear wave-wave interactions and dissipation due to bottom friction in shallow water. The Source term for wave-wave interactions is based on a simple, but directionally-responsive, formulation given by Young (1988). The model has been tested against the SWAMP (1985) results and for real winds for storms in the Irish Sea and elsewhere.
