Dynamic dune management in practice

The themeday

We invite you for the NCK themeday on 'Dynamic dune management in practice' to share and discuss our latest insight in dynamic dune management from recent projects like Spanjaards Duin, Hondsbossche Duinen and Prins Hendrik Zanddijk. In these projects one of the largest challenges is the balance between allowing dynamics for nature and flood safety functions. And, since these projects have created dune areas from scratch, they require an adaptive approach. We would like to discuss the value of these kinds of projects for coastal research in general and the Dutch coastal landscape. We hope the lessons will inspire future applications. And we are proud to show you the area of Spanjaards Duin at the start of the themeday!

The project and management of Spanjaards Duin: dynamic if possible and adaptive is needed

Spanjaards Duin was constructed at the coastal stretch near 's Gravezande (NL) as nature compensation for Maasvlakte 2 in the winter of end of 2008 - beginning 2009. For the first time, marine nourishment sands were used to construct a dune area which should accommodate extensive areas of high quality grey dune and dune slack vegetation within a set time frame of 25 years. Growing a high-quality nature reserve from marine bare sands does not happen by itself. A unique area has been created, through cooperation and learning by doing of dredgers, policy makers, nature area managers, ecologists, earth scientist and civil engineers, all aiming to achieve the nature compensation target using their specific skills.
