Abstract

A two dimensional numerical hydrodynamic model including various turbulence models has been developed and applied to predict the stream induced circulation in a square river harbour. The turbulent flow was driven by a stationary current in an adjacent model river. Emphasis has been focused on comparing different turbulence models including: the depth-integrated mixing length, k-E and algebraic stress models to predict accurately the velocity patterns within such basins. The finite difference method has been used to discretize the governing equations. For the solid boundaries the common no-slip boundary representation has been selected for the turbulent diffusion terms in the hydrodynamics equations. Moreover, the advective acceleration terms in the hydrodynamics equations were treated using the third order upwind scheme whereas the counter
