Abstract: This paper presents a numerical solution for the bottom boundary layer (BBL) in the surf zone. The upper boundary of the BBL is determined through the solution of a 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 of horizontal velocity can be found out through the solution of the governing equations of the BBL.
