【 摘 要 】

This paper presents a numerical solution for the bottom boundary layer (BBL) in the surfzone. The upper boundary of the BBL is determined through the solution ofa breaking waves model. Different turbulence models have been tested to determine the distribution of turbulent kinetic energy, energy dissipation and eddy viscosity in the BBL. Finally, the vertical profiles ofhorizontal velocity can be found out through the solution ofthe governing equations ofthe BBL.
