Marine Extremes Transforming coAsts - pathways for coastal adaptation across scales

Inland drainage and risks from combined flooding events

Under the title 'Ways to improve risk management in the area of marine extreme events and natural hazards' (mareXtreme) of the third DAM research mission (German Marine Research Alliance), four joint projects are focussing on the protection and sustainable use of coasts, seas and oceans in a regional, national and international context.

In the METAscales project, the physical-oceanographic risks are being analysed using the North Sea coast as an example in order to improve forecasting capability. In the long term, the aim is to increase resilience by optimising the planning process.

Within this framework, the department HydRiv is investigating problems and adaptation requirements in relation to extreme marine events with regard to combined flooding events (compound floods) in coastal lowland areas. Based on the data (e.g. area drainage volumes) compiled in the SiSchöMo project we will analyse the Maadesiel  area near Wilhemshaven exemplary with regard to flooding risks. This domain is drained either by a sluice or by pumps depending on the tidal water levels. For this purpose multi-variate statistical analyses of the occurrence of compound floods are carried out for current situations as well as future developments. Furthermore, a model chain will be developed that maps the relevant hydrological, hydraulic and impact processes for a risk analysis. The model chain is used to estimate the effects of future changes in the area and drainage boundary conditions, particularly for extreme events. Based on this, adaptation requirements are recognised and possible adaptation options investigated.
