Various methods and systems exist for realising temporary flood protection. Besides movable panels and bulkheads, water fillable tubes can also be used.

Waterproof bulkheads

The system consists of vertical H-sections which are attached to the foundation. Hollow aluminium beams are attached between the sections.

Water fillable tubes

The benefit of these facilities is that they can help control and protect an entire area at once. Since their management, maintenance and repairs and operation are in public hands and do not depend
on the views and cooperation of private individuals, they are more reliable. However, the costs are relatively high, and they add nothing to the town or city’s aesthetic appeal. These systems are suitable for protecting existing areas and can be realised around existing constructions.
