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
 …

9. THESE 4 – JOOST VEER
