Abstract
Steepness-limited wave breaking is simulated in a fully nonlinear potential flow model and validated with laboratory data. Breaking onset is based on the ratio of horizontal particle velocity at the crest, relative to the crest velocity reaching a threshold value. A breaking dissipation model, where the non-dimensional breaking strength parameter is predicted based on the linear wave steepness is used. A new time-dependent dissipation is tested, and the breaking termination criterion is studied.References
