Abstract: A two-dimensional fully coupled depth-averaged morphodynamic model, including modules of currents, waves, sediment transport and bottom evolution, has been set up to predict the medium-scale morphological evolution in the Meldorf Bight on the North Sea coast. This paper describes how highly parameterised tidal and wave conditions can be extracted from long-term data to form a morphologically representative climate, followed by a qualitative comparison of the results of a 5 year simulation to several sets of field data. The predictive ability of the model with respect to the general morphodynamic trends in the tidal channels and shoals as well as the evolution of specific channel cross-sections has been evaluated. The results obtained show good agreement with morphological and sub-bottom profiles measurement data taking into account that model calibration and optimisation was not undertaken.
