Research paper thumbnail of North-Sea Model of the BAW: Simulation of Tidal Dynamics in the North-Sea with focus on the German Bight

This model is used in-house to generate the boundary conditions for estuary modelling and to estimate tidal and storm surge dynamics. The model set-up is based on an unstructured mesh (triangular grid), which provides a good representation of the complex topography in coastal areas, in the German estuaries, and in the entire North Sea. This guarantees that the interactions between coastal zones and estuaries are accurately simulated without the adverse effect of artificially specified model boundaries.

Especially in the shallow near coast areas, changes of the MSL result in a significant modulation of the shallow water constitu-ents. These coupled non-linear effects can be proved in the German Bight and up to the estuaries by analysing the differences in the harmonic constants of the tide. In the mouth of the estuaries the tidal currents will raised up due to more flooding of intertidal flats. This changes the whole tidal dynamics of the entire estuary. With reference to the Elbe estuary this result in a significant rise of the tidal high water and the tidal range upstream to the harbour of Hamburg. By the help of a hydrodynamic-numeric model of the North Sea, including the German Bight and the estuaries, changes in the partial tides and the tidal characteristic numbers can be evaluated. The above mentioned effects can ...

This guarantees that the interactions between coastal zones and estuaries are accurately simulated without the adverse effect of artificially specified model boundaries. The optimisation of this grid fulfils the requirements of the newest computational programmes and is generally applicable to several simulation codes.

Sie werden nicht nur zur Analyse zurückliegender Zeiträume eingesetzt, sie sollen auch die Analyse von zukünftigen Veränderungen ermöglichen. Prozessbasierte Simulationsmodelle erlauben insbesondere die systematische Untersuchung von Zusammenhängen, die sich in der Natur der Beobachtung entziehen oder nur mit großem Aufwand zu erfassen sind. In diesem Artikel werden Ergebnisse basierend auf großräumigen morphodynamischen Simulationen mit unterschiedlichen Modellsystemen präsentiert. Der Zeitraum umfasst die Jahre von 1996 bis 2008 und berücksichtigt die treibenden Kräfte von Gezeiten, von Fernwellen, von Oberwasserzuflüssen sowie von Windfeldern und dem daraus generierten Seegang. AufMod stellt jährliche konsistente Bathymetrien und initiale Sedimentdaten bereit, die von den morphodynamischen Modellen für ...

These ambitious goals require a tremendous amount of careful planning and considerations, which depends heavily on data availability. For this reason, we established in close cooperation with stakeholders an open-access integrated, marine data collection from 1996 to 2015 for bathymetry, surface sediments, tidal dynamics, salinity, and waves in the German Bight for science, economy, and governmental interest. This second part of a two-part publication presents data products from numerical hindcast simulations for sea surface elevation, current velocity, bottom shear stress, salinity, wave parameters and wave spectra. As an important improvement to existing data collections our model represents the variability of the bathymetry by using annually updated model topographies. Moreover, we provide model results at a high temporal and spatial resolution (Hagen et al., 2020b), i.e. model results are gridded to 1,000 m at 20-minute intervals (10.48437/02.2020.K2.7000.0004). Tidal characteristic values (Hagen et al., 2020a), such as tidal range or ebb current velocity, are computed based on the numerical modeling results (10.48437/02.2020.K2.7000.0003). Therefore, this integrated, marine data collection enables coastal stakeholders and scientists to easily enter and participate in countless applications, which could be the development of detailed coastal models, handling of complex natural habitat problems, design of coastal structures, or trend exploration into the future.
