Summary of the research
Many tidal basins, such as those in the Wadden Sea (Netherlands, Germany, Denmark), are characterized by intricate channel-shoal patterns that experience periodic drying-flooding. In order to better understand hydrodynamics and morphodynamics of tidal basins, particularly taking into account the geometrical (multi-scale) complexity of channel-shoal patterns, subgrid modelling (using the 3Di software package) will be used to provide a computationally attractive process-based way of modelling tidal basins.
However, till now subgrid modelling has not yet been applied to tidal basins of the Wadden Sea. Furthermore, the process of bank erosion – which is considered important for the evolution of the channels including inlet and basin is only poorly understood. Therefore, Laboratory experiments will be conducted at UC Louvain (Belgium) leading to a bank erosion formulation that can be implemented and tested in the subgrid model. Finally, we aim to conduct a large-scale morphodynamic model application to investigate long-term evolution of channel-shoal patterns in the Wadden Sea.
