Abstract

This paper presents a breaking waves model in which the wave boundary layer and the swash zone are also included in the model domain. The model is based on the Reynolds equations for incompressible turbulent flows. The numerical solution of the model is performed in a non-uniform grids system so that high resolution can be obtained in the near-bottom area, where the velocity gradients are very large due to viscous effect. Numerical results of the present model are verified by laboratory data for the surf zone, the bottom boundary layer and the swash zone. The comparisons show that the model can predict reasonably the water motions in the surf zone, the bottom boundary layer and the swash zone.
