Resilience measure: Creation of a second dike line


A second dike line is created by building other dikes, mostly bigger dikes, on the water side of existing dikes, which will not be removed. Building of new and bigger dikes can be necessary due to e.g. increased storm surges activities (higher water levels, more frequent occurrence of storm surges). The newly built dike provides the protection against the storm surges. The still existing dike is then referred to be the second dike line (or summer dike) and provides a further protection by creating an additional volume that can be flooded.
