A three dimensional numerical model which simulates the transport processes in stratified coastal waters is presented. The model computes the full spatial distribution of velocities of unsteady flow induced by wind, tide or water density differences. The model consists of hydrodynamic, transport and turbulence model components. The governing equations written in the Cartesian coordinates, are solved by the Galerkin Weighted Residual Method. in the vertical plane and by finite difference approximations in the horizontal plane. The water depths are divided into the same number of layers following the bottom topography. Therefore, the vertical layer thickness is proportional to the local water depth. Higher resolution can be achieved either by increasing the number of layers, or by grid clustering. The governing equations are solved implicitly. The finite difference approximations can handle the variations in the horizontal mesh sizes. The flooding and drying processes can be considered in the treatment of shoreline boundaries. The model is applied to Marmaris Bay located at the Aegean Sea coast of Turkey. Circulation patterns induced by the wind and the tidal action are simulated.
