Abstract: The structure of the flow field in harbour basins shows significant three-dimensional (3-D) effects, e.g. variation of the direction of the horizontal velocity components with depth, existence of vertical velocity components which are not negligible and nonuniversal distribution of turbulence. These features have been investigated by means of a numerical 3-D free surface model based on the finite element approach with parameterization of turbulence by mixing - length formulation and Neumann boundary condition for the walls. The numerical simulations are made for two different small scale harbour variants. The investigations concern the simulation of the flow fields as well as the analysis of the turbulence structures. The results of the numerical simulations are compared with measurements obtained from a physical model.
