Short summary
Due to climate change, an accelerated mean sea level rise is expected. Numerical hydrodynamic models help to understand how mean sea level rise changes tidal dynamics. One limiting factor is the resolution of the model grid. In this study we show that especially in flat coastal areas such as the Wadden Sea in the German Bight the representation of the bathymetry plays a crucial role for the estimation of changed tidal dynamics in response to mean sea level rise.
