The first solution consists of a gradual strengthening of the quay, every 12 years. Therefore the dike does not need to be heightened extra in order to compensate for subsidence of the dike. The dike on Marken is rather sensitive to this due to the specific soil profile of clay and peat. Consequently, the dike can remain lower and more compact in line with the current qualities.
'New quay' solution
In this approach the current quay will be replaced by a new one and will be built beyond the dike. Firstly, the subsurface will be improved to ensure the dike is less sensitive to setting. For the Rozewerf, a customized solution was developed together with the residents. The old quay will be maintained and a harbour will be built serving as a transitional construction between the old and the new quay.
