The laminar free surface boundary layer beneath a solitary wave is investigated using numerical simulations. Across the boundary layer and are comparable in magnitude, where is the velocity, position and subscripts and refer to components tangential and normal to the free surface. In this region is approximately constant across the boundary layer while varies with and outside the boundary layer tends to . The numerical results are compared to analytical models and good agreement is found.
