MEDAM : THE INVENTORY
Assessment of the overall impact of reclamation from the sea has been undertaken on the basis of an exhaustive inventory :
- of the natural coastline (historical survey prior to any reclamation),
- of the original surface areas of shallow bottoms (historic surface areas: prior to any reclamation). The bathymetric ranges 0 to -10 m and -10 m to -20 m have been taken into account,
- of all reclamation greater than 100 m² (harbours, landfills, dykes, breakwaters, groynes, etc.). The artificialised coastline and the areas occupied by constructions are included in the inventory.
