Current study is refinement and application of a two-dimensional horizontal numerical model to predict geo-morphological changes in tidal basins. An ADI finite difference algorithm has been used for solving the governing equations, which consist of the conservation of mass and momentum for the hydrodynamics, the transport equation for suspended sediment fluxes and the sediment mass conservation equation for bed level changes. The model includes three criteria for the initiation of motion (i.e. Shields (1936), Kolahdoozan (1999) and Zanke (2003)). Since the flow is turbulent, its components have a random nature and sediment transport processes can be expressed by stochastic approaches. In this study both deterministic and stochastic methods were included in bed load computations. Verification of model results have been carried out by an experimental study cited in the literature. Comparisons of results for different criteria for the initiation of motion shows that the unsteadiness parameters of current have a major effect on the bed level changes in comparison with turbulence structure of the flow.
