Deltares: Galgeplaat Sand Nourishment Good for Nature (The Netherlands)

The Galgeplaat sand nourishment trial in the Eastern Scheldt was completed recently.

The result is positive. Nourishment stops the Galgeplaat tidal flat eroding as quickly and nature is recovering well. And there has not been any negative effect on mussel farming in the area.

The nourishment operation is intended to mitigate the negative impact of ‘sand starvation’ in the Eastern Scheldt. The Eastern Scheldt is home to intertidal flats that fall dry during ebb tides. But more and more sand from these flats is being lost to the tidal channel of the Eastern Scheldt, eroding them so that they disappear under water. That has a negative impact on biodiversity because the flats are home and a source of food to many birds and other organisms. And they are also natural breakwaters that mitigate the impact of waves on dikes. Coastal defences have to be strengthened when the flats erode.

The trial provided us with more information about nourishment as a possible way of counteracting the negative impact of sand starvation in the Eastern Scheldt. In addition, Building with Nature studies were carried out at a range of other locations in the Eastern Scheldt, including trials with oyster reefs. The combined results of these trials should develop the knowledge needed over the next 50 years to conserve this unique intertidal area.

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.
