Building with Nature


 24.3.17

Danish Coastal Authority is part of the Building with Nature InterReg project

The Danish Coastal Authority (DCA) is part of the interregional EU-project ‘Building with Nature’ together with partners from the Netherlands, Germany, Scotland, Sweden, Norway and Belgium. The purpose of the project is to investigate how natural forces are used to build, construct or maintain coastal protection schemes. The overall objective is to make coasts and catchments of the North Sea Region more adaptable and resilient to the effects of climate change. The project will focus on cost-efficient coastal protection schemes like sand nourishment and coastal dunes as a natural protection of the hinterland for erosion and flooding. BwN uses state-of-the-art methods for transnational analysis of seven coastal resilient laboratories. This will generate improved knowledge for municipalities and citizens to handle coastal erosion under recent and future climate conditions by implementing cost-efficient coastal protection schemes. On the basis of this improved designs and business cases will be developed, which can be used by citizens, engineers and policymakers to optimize coastal protection schemes. This allows well-documented BwN solutions to be incorporated into national policy and investment programmes in the respective countries.

DCA’s research areas

DCA encompasses seven research areas within this project. The purpose of doing research within these areas is to develop design guidelines for sand nourishments in Denmark. This is obtained by analysing coastal dynamics and different nourishment designs in both national and international perspectives. The analysis will be carried out in corporation with the other countries in order to establish synergy and knowledge transfer between the BwN partners. Handling of erosion problems by implementing sand transport reducing methods will be investigated through analysis of wind-driven (aeolian) sand transport fluxes at selected study areas. Furthermore, a sediment budget of the Wadden Sea will be calculated in corporation with Schleswig-Holstein for investigating whether the sedimentation rate of the Wadden Sea is able to keep up with relative sea level rise in the region. The resulting sediment budget can be used as a basis for managing the Wadden Sea and securing the area to future climate conditions by improving strength of seadikes.

Improved knowledge will generate better guidance and cost-effective projects

DCA expects that this InterReg project will benefit the guidance of coastal protection projects to become more adapted to climate change trough transnational research with the involved partners. With improved knowledge the coastal protection will be optimised and become more cost-effective. The gained knowledge from this project will be available for citizens, municipalities and engineers, for example as national guidelines for sand nourishment strategies. The project will run over a 4-year period from 2016-2020 and the EU finances 50 % of the Danish part of the project.
