The project Roggenplaat nourishment is a project in the Oosterschelde basin that aims at safeguarding the eroding Roggenplaat tidal flat for nature and safety. The intertidal flats and shoals have two important functions in the basin. Firstly, they are valuable habitat and foraging grounds for many migrating and wintering waterbird species; for this reason the Oosterschelde is an important N2000 area. A second function of intertidal foreshores is to reduce the wave attack on surrounding water barriers and dikes.
After several pilot projects in the Oosterschelde, Rijkswaterstaat decided to do a large-scale nourishment on the Roggenplaat tidal flat, one of the largest tidal flats in the Oosterschelde that suffers severely from erosing due to the so-called sand starvations in this basin. The project Roggenplaat nourishment is part of the Planning phase (2015-2017). The Planning Phase will start with the T0 monitoring, the set-up of a long-term monitoring programme and the design of the nourishment. This project will contribute to a better understanding of the eco-morophological functioning of intertidal habitats and how to manage and conserve these valuable habitats. The project is an example of a Building with Nature approach that make use of the properties of nature to develop/conserve nature areas that at the same time form robust and climate proof coastal defence systems.
