Outline NatureCoast What has been studied? Understanding the behaviour of the Sand Motor Utilizing integrated knowledge Spinoffs
Motivation for interdisciplinary research • Large signal to noise ratio • Multifunctionality requires interdisciplinary science • End-user involvement in definition of research questions
NatureCoast Research Program • Interdisciplinary research project • Funded by STW – Dutch Science Foundation (5.5 mln € ) • 6 universities, 12 PhDs + 3 postdocs • Strong involvement of end-users • Builds on MEP, EFRO and NEMO (3 PhDs) • International collaboration with universities Monitor Understand Create

Governance
Province South Holland key figure • Ministry invited provinces for integrated ideas • Province of ZH was Initiator • Opportunity-oriented instead of problem-oriented • Convincing all stakeholders

What was unexpected? • Dunes need more time to develop and lower growth rates • Vegetation needs more time to develop • Intertidal area is main sand source for aeolian transport • Channel breach cycle is longer than expected (5 years) • Steep slopes and strong bed forms in channel • Cliff formation • Liquefaction / quick sand • Kitesurfing hotspot
Utilizing Integrated Knowledge • Through Ecosystem Services in Design • Develop integrated tools for quantification • Verification through international cases • Exploring governance setting Monitor Understand Create
Alexander van Oudenhoven Consequences of Post-doc at Leiden University Sand Motor design to human well-being M. Van Puijenbroek RWS / Joop van Houdt • Shape (hook, island, parallel) Coastal Protection Erosion Prevention • Extent, height, orientation • Grain size of material Dunea @DeZandmotor • Other (chemical) properties Fresh water provision Recreation • (Permanent) infrastructure @DeZandmotor • Management (raking, etc.) Inspiration for Report ARK 2016 culture, art & design Habitat provision and others..
Arjen Luijendijk Post-doc at Delft Univ of Technology / Deltares Integrated tools for ESS quantification • Long-term predictions with coupled models • Combining hydrodynamics, morphology, aeolian transports, groundwater, vegetation, and habitat development 20 year prediction
