Operation of the Storm Surge Barrier
Wetted works (sill structure)
The sill structure on the bottom of the
New Waterway has three functions:
- The formation of a flat base and foundation for the retaining walls,
which are positioned on the sill-
blocks with the aid of fenders.
- Cutting down the flow of water once the barrier is closed.
- Holding in place the subgrade on which the blocks are based.
- Bottom protection and filter-bed
- Dredging works
- Raking the surface
- Dumping the filter-bed
