Growing dyke: protecting our coastline

With the Meegroeidijk, we are responding to sea level rise without dyke make major changes to the dyke . Whereas dike reinforcement normally takes years, we are building the dyke layer by layer dyke the top dyke . We are using silt from the port of Lauwersoog for this purpose. In doing so, we are contributing to better water quality in the Wadden Sea.

How does the dyke respond dyke a layer of silt?

We are investigating how the grass cover reacts to the applied silt. Does it simply grow through the new clay layer? How strong is the new turf? And are there perhaps special grass mixtures that perform particularly well? The silt we applied earlier has already matured into clay and adheres to the grass cover. That is promising.

The Meegroeidijk is a collaboration between the Brabantse Delta Water Authority and the Rijnland Water Authority. The Meegroeidijk is largely financed by STOWA, the Flood Protection Program, and the Interreg project BONSAI. Four countries are participating in Bonsai: Belgium, Germany, France, and the Netherlands. The project will run until 2029. The total joint budget is €10,699,561.10, of which €6,419,736.62 comes from EU subsidies.
