DIKE FUNCTIONS
The primary function of dikes is to prevent flooding. But for centuries, they
have also had other functions. Sheep graze on them and they are used for
recreational activities. Houses are built alongside them and we also build
roads on them. Sea-level rise, increased river discharge, land subsidence
and new standards mean that flood protection needs to be improved in
many areas. However, upgrading flood defences frequently gives rise
to public opposition. Local people fear that the quality of their living
environment will be adversely affected. This constitutes a major challenge
for local managers.
THE MULTIFUNCTIONAL DIKE NOW…
Dike houses
The houses have been built next
to the dike because of the access
road. So there is limited room
to strengthen the dike. The only
options are structural measures or
the demolition of the houses.
Foreshore
Sheep and cows can graze
on the foreshore and there
is room for recreation.
