Abstract
In this paper, a curvilinear Boussinesq model is further improved in order to be used in more practical applications. Firstly, the energy dissipation due to wave breaking is considered by introducing an eddy viscosity term into momentum equations. Secondly, the slot technique is introduced into the curvilinear model for simulations of wave run-up/run-down in swash zones. Thirdly, Smagorinsky subgrid lateral turbulent mixing is utilized to account for the effect of the resultant eddy viscosity on the wave-generated underlying flow. In addition, a TMA spectral wave maker is implemented in the model for simulations of irregular waves. Finally, the model is used to simulate wave propagation in Ponde de Leon Inlet. Model/data comparisons show the fully nonlinear Boussinesq model give accurate results for nonlinear wave transformation over irregular bathymetry. It is also shown that the curvilinear model is an efficient model for wave computations in large computational regions with complex geometry.
