This document summarizes a workshop on dynamic coastal management. The workshop included introductions and short presentations from Luc Geelen, Joost Veer, and Gerben Ruessink. Gerben Ruessink's theses discussed using small beach nourishments and foredune trenches to stimulate dune remobilization, but that too much sand leads to excessive coastline growth. He advocated for a dynamic assessment tool to evaluate coastal health. Joost Veer's theses argued that integrating nature and safety is the best way forward, and that not conducting nourishments will not lead to short-term dune dynamics or mobility.

4. THESE 1 - GERBEN RUESSINK
 The combined use of small (beach)
nourishments and foredune trenches will
additionally stimulate dune remobilization
 Critical issues:
 Type of sand (e.g., shell content)
 Amount of sand

5. THESE 1 - GERBEN RUESSINK
 Too much sand leads to an obese coast

6. THESE 2 - GERBEN RUESSINK
 Dynamic coastal management demands a
dynamic assessment tool: from a safe coast to
a healthy coast
 Elements:
 Sufficient sand
 Geomorphologic dynamics (sand needs to move!)
 State of ecosystems
 …

7. THESE 2 - GERBEN RUESSINK
 Dynamic coastal management demands a
dynamic assessment tool: from a safe coast to
a healthy coast

8. THESE 3 – GERBEN RUESSINK
 Dune erosion is inherent to beach-dune
interaction and should not be prevented by
large-scale (beach) nourishments

9. THESE 4 – JOOST VEER
 Best way forward = Integrate Nature & Safety

10. THESE 5 – JOOST VEER
 No nourishments will not lead to Dynaims in
the front dunes on a short term
RESPONSE IN FOREDUNE MOBILTY TYPE

11. THESE 6 – JOOST VEER
 more space = more functions?
