The aim of this study is to understand the impact of the way we parameterize sediment transport processes on the development of sand wave shapes and thereby improve the ability of our morphological models to predict in-situ sand wave dynamics in different areas. To this end 2DV hydro-morphodynamic Delft3D FM sand wave models were created for two case study locations (HKZ and Texel, see publication for details) in the Dutch North Sea. These models were run for the period between two bathymetric measurements (2008-2010 at Texel and 2012-2016 at HKZ) to allow for morphodynamic validation. To test the influence of different sediment transport formulations models were run with both the Van Rijn 1993 and the Van Rijn 2007 transport formulations. These were combined with varying values (0.5-5) of the longitudinal bed slope parameter (alpha_bs). The simulations revealed that the Van Rijn 2007 formulation, which predicts relatively lower transport rates, and thus allows for lower bed slope-induced transports, is better capable of preserving the steep slopes of sand waves, while limiting sand wave growth. Lastly, for the best performing settings a model was run using only tidal forcing to test the influence of non-tidal hydrodynamics. This dataset contains the model input and outpur for these runs.
