7.6 Extreme Sea Level Scenarios (Future Projections)

Scenarios of future extreme sea level events are needed not only for planning of
sustainable coastal development but also for catastrophe management. Generalizing
Eq. ( 1 ) we introduce a field MAX into the formula

DEM t = DEM 0 − EC t + GIA t + MAX, ∀ t > 0 (3)

MAX stands for the highest sea level measured within the area of interest. This
approach is similar to the recommendation to estimate the defence water level for
coastal protection constructions (Oumeraci and Schüttrumpf 2002 ) . For the western
Baltic Sea we model a scenario for t = 150, which means a possible sea level event
