In her thesis van Loon investigates if and how the same or an even higher level of safety can be achieved in the Wadden region by means of creating a flood defence zone that favours, besides flood protection, nature and landscape values or heritage, recreational, and even economic values. While all available innovative flood defences are considered, special attention is given to the role of salt marshes in this context.

Integration of salt marshes into long-term adaptation strategies is very promising for the Wadden region, especially for dike sections where salt marshes are already present or developing. Vegetation is a major factor in the wave damping capacity of salt-marsh forelands, therefore it is important to take into account the zonation of different plant. Furthermore, the thesis reveals that in salt-marsh restoration, the goals of flood protection and nature and habitat conservation and enhancement can be mutually reinforcing.long-term adaptation by combining functions in flood defences in het auditorium van de Universiteit Wageningen.
