This dataset contains the results of the hydrodynamic simulation of the storm surge of October 20 and 21, 2023, which caused exceptional water levels on the German and Danish Baltic Sea coasts. The event was reconstructed on the basis of water level measurements, meteorological reanalyses and high-resolution bathymetric data. The data was then validated against the available water level observations with a high accuracy. The aim of the simulation was to use a hydrodynamic-numerical model to describe and analyze the complex hydrological processes of the storm surge in detail in order to gain insights into the degree of filling of the Baltic Sea, the progression and peaks and the duration of increased water levels. The results are to be made available across the entire area so that they can be used for further risk analyses in order to minimize damage from future storm surges.Further descriptions are made in Beckmann et al. (2024).
