Delft3D FM numerical models for North Sea case studies with varying tidal and non-tidal forcing included in Coastal Engineering article: "The importance of time-varying, non-tidal currents in modelling in-situ sand wave dynamics"

This dataset contains the model input and output for the Delft3D FM model runs used in the research article:Overes, P. H. P., Borsje, B. W., Luijendijk, A. P., &amp; Hulscher, S. J. M. H. (2024). The importance of time-varying, non-tidal currents in modelling in-situ sand wave dynamics. Coastal Engineering, 189, 104480. https://doi.org/10.1016/j.coastaleng.2024.104480The aim of the study is to assess the impact of realistic fluctuations of non-tidal currents on in-situ sand wave dynamics. This is done through comparison of the results of various 2DV hydro-morphodynamic Delft3D FM sand wave models with different forcing. The models include two case study locations in the Dutch North Sea (HKZ and Texel, see publication for details). For each of the case study location models with different hydrodynamic forcing are set up, which include different combinations of tidal components and a full forcing run which also takes meteorological forcing and density driven effects into account. From the morphological results it is concluded that the time-varying, non-tidal currents, which are included in the full forcing run, but not in the tidal runs, have a significant effect on the dynamics of sand waves. The dataset includes the model input and output for these different runs.

本数据集包含研究论文中使用的Delft3D FM模型（Delft3D FM）运行的模型输入与输出数据，该研究论文为Overes, P. H. P.、Borsje, B. W.、Luijendijk, A. P.与Hulscher, S. J. M. H.于2024年发表于《Coastal Engineering》的《时变非潮流对原位沙波动力学模拟的重要性》，文章编号为104480，DOI：10.1016/j.coastaleng.2024.104480。本研究旨在评估非潮流的真实波动对原位沙波动力学的影响，具体通过对比不同强迫条件下多款二维垂向（2DV）水动力泥沙动力Delft3D FM沙波模型的模拟结果开展分析。模型选取荷兰北海的两个案例研究区域（HKZ与Texel，详细信息参见发表论文）。针对每个案例研究区域，我们搭建了不同水动力强迫条件的模型，其中涵盖不同潮汐分潮组合的工况，以及同时考虑气象强迫与密度驱动效应的全强迫工况。从泥沙动力模拟结果可知，全强迫工况中包含但常规潮汐工况未纳入的时变非潮流，对沙波动力学具有显著影响。本数据集包含上述各类模型运行的输入与输出数据。关于不同文件的具体说明，请参考用户手册：https://content.oss.deltares.nl/delft3dfm2d3d/
