A BOUSSINESQ MODEL FOR BREAKING WAVES: COMPARISONS WITH EXPERIMENTS

Jayaram Veeramony, Ib A. Svendsen

Abstract


The paper describes results with a breaking wave model based on an extended set of Boussinesq equations. The wave breaking is described by accounting for the effect of vorticity generated by the breaking process. The vorticity field in the domain is obtained by solving the vorticity transport equation, which is based entirely on the Reynold's equations. In addition to the wave height decay and profile deformation predicted by earlier breaker models, the present model also provides information about the velocity profiles. The model results give good agreement with experimental data for wave height, setup and the velocity profiles. The crossshore variation of the radiation stress calculated from the model results gives a good representation of the results from experimental data.
