Water leash — Métropole 2017 — CD Carthage

Description

The water mark consists of: — the leash of the highest waters (limit of land never covered by the sea), the continuity of which is ensured throughout the BDCarthage. In the case of islands, it shall be seized only if it delimits an area of an area greater than or equal to 1 hectare; — the leash of the lowest water (limit of the still submerged land), where it is more than 100 meters away from the upper water mark (if not seized) and outside the estuaries (where an arbitrary line closing the estuary is seized instead of the lower water mark). In the case of the islands only at low tide, it shall be seized only if it delimits an area of an area greater than or equal to 4 hectares. A leash section is located by geometric arches, corresponding to the cuttings by attributes managed by the IGN: nature. Changing the value of an attribute only results in the creation of a leash section if the new value remains constant over a length of at least 1 km.
