New Coastal Protection for Cadzand

During a regular safety check of the Dutch coastline several locations were identified where the coastal protection is unable to withstand a 4,000 years super storm.

These locations are seen as weak links in the Dutch coastline.

In Cadzand Bad, located close to the Belgian border in the Dutch province Zeeland, an important dewatering sluice system was found to be one of these weak links.

Measures were therefore required to upgrade the safety of this sluice.

The coastal resort Cadzand-Bath has taken this opportunity to enhance its attractiveness alongside the essentially necessary safety measures.

In order to improve the safety at the location of the dewatering sluice, there were 2 options:

  • to increase the crest level of the structure, or
  • to reduce the wave heights in front of the structure.

Since it was found impossible to increase the crest level of the structure, 2 breakwaters are being constructed to reduce the waves in front of the sluice.


Between those breakwaters, a marina will be built providing space for up to 125 leisure boats. The new breakwaters will be extended to nine meters of water depth (total length 550m and 350m) to limit sand intrusion into the outlet and marina.

The breakwaters are protected by Xbloc® armor units of 4 and 10 tons, which were tested during physical model tests at BAM’s hydraulic laboratory in Utrecht, the Netherlands.

The Xblocs® are produced in the Belgian seaport of Zeebrugge and are shipped to site. A barge offloading facility has been built to offload the Xblocs and the rock materials which are also delivered to site by sea. Due to material delivery by sea disturbances during tourist peak season can be avoided as much as possible.

Detailed Design of the breakwaters has been prepared by BAM Infra.

The construction works are carried out by the teams of BAM Infra and Martens en Van Oord.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews ( holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
