SIMULATION OF STEEPNESS-LIMITED BREAKING WAVES IN A FULLY NONLINEAR POTENTIAL FLOW MODEL. (2023). Coastal Engineering Proceedings, 37, waves.24. https://doi.org/10.9753/icce.v37.waves.24

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.
