The challengeThe Hoorn - Amsterdam dike section forms part of a ring of water barriers that protects the province of North Holland. According to the current standards, the stability of the dike can no longer be guaranteed under extreme conditions such as long-lasting high water levels on the Markermeer. It is necessary to reinforce the dike (over approx. 33 km) to be able to continue to protect the population and the land against flooding. The dike needs to be reinforced in an area with very soft ground (peat), protected rural views, a rich cultural history, a main ecological network, an intensive recreation, and a somewhat limited access.
The solutionThe purpose of the dike reinforcement is to guarantee the safety of the dike section for at least 50 years. The objective is to create a safe, future-proof water barrier that is appropriate to its environment. The existing functions and valuable elements are retained as much as possible and the opportunities for these aspects are utilised.
Water Board Hollands Noorderkwartier has commisioned Royal HaskoningDHV not only to work out the details, but also to play an important role in the project management and process management, in the internal and external communication and in developing a vision for the project.
