Fig. 7.8 Reconstruction of the sea level within the western Baltic Sea during the storm event and
flood of November 1872. The map presents the maximum values for the time between 4 and 14
November 1872 of the hindcast given by Rosenhagen and Bork ( 2009 )
For planning of coastal protection activities local models in a higher resolution
are needed. In Fig. 7.10 , a local extreme water level scenario is given for the
Wismar Bight. In the centre of the Bay the navigational channel directing to
Wismar Harbour is clearly visible. Areas endangered to be flooded during an
extreme storm surge are marked red. It is obvious that coastal meadows, in
particular fragile peninsulas and bars, are at risk of flooding and erosion. The core
of Wustrow Peninsula detaching the “Salzhaff” lagoon from the Baltic Sea would
be separated in case of a storm surge from the mainland and the sandy bar in the
NW of the map in Fig. 7.10 would be washed over and exposed to the physical
Fig. 7.9 Extreme sea level scenario for 2100 AD at the western Baltic Sea, combining secular
trends in neotectonic displacements (vertical crustal movement), climatically controlled sea level
rise based on IPCC scenario, and gauge reconstruction for the coastal flood in November 1872.
Red colour marks areas of potential coastal hazards. The Wismar Bight used for the local scenario
in Fig. 7.10 is marked at the southwestern coast. The scenario is generated under the theoretical
assumption that no coastal protection activities will take place
