Abstract

Applicability of two well-regarded Boussinesq-type equations in simulating evolution of nonlinear water waves and currents over submerged breakwaters is further investigated. An artificial energy dissipation term is introduced to overcome unrealistic flow patterns that lead to numerical instabilities near abrupt depth configurations. The predictive skills of the models are investigated using new set of experimenlal data. The simulated wave height, mean water levels, and nearshore circulation patterns show good agreement with the experimental data, if the breaking induced energy dissipation sub-model is properly calibrated.
