  1. De moeren IRIS VANDENBULCKE & LOUISE VERHUE IMMACULATA INSTITUUT BELGIUM

  2. Content Situation Height Mud flats (slikken) & saltmarsh (schorren) Human interventions

  3. Situation Little region in the west of our country near the sea Relief feature: sealine: flat difference in height: minimal height: 0-5 m = LOWLAND

  4. Height Normally, without dunes, dikesorsluices, the polders by high tidewouldbepartiallyinundated & by spring tideitwould even becompletelyinundated. Mud flat (slikken) & saltmarsh (schorren)

  5. Mud flat (slikken) Notovergrown Undersealine Overflows 2 times a dayby high water Clay & sand

  6. Saltmarsh (schorren) Overgrownwithgrass & reed Abovesealine Overflows 2 times in a month Clay

  7. The difference Salt marshes are overflowedonlybyspringtime Mud flats are alwaysoverflowedby high water On mud flats there are aquatics

  8. Humaninterventions Dikes (abdij Ter Duinen in Koksijde) protectionby storm surges The old seadike (De oude zeedijk) 1060 Natural drainage by gravitation: construction of canals send excess water to a lock Artificial drainage bywindmills

  9. What infrastructure had to be successively applied for this? Ring dike Ring lock Drainage canals Mills

  10. Natural drainage bygravitation

  11. Ring dike

  12. Wind wheel Archimedes screw
