Issue

Flood hazard

An increased flood hazard because the flood defence does not meet the requirements and/or due to extreme conditions.

Because of the rising water level, dikes have to be heightened to continue meeting the norms.

Solution

Moving the dike

In several places, the dike is lowered so it can flood during highwater events. This can provide a water level decline of 35 cm. The expectation is that this will occur once every 25 years.
