Abstract

L’invention concerne une algue artificielle (S) caractérisée en ce qu’elle comprend - un moyen d’ancrage (A) pour ancrer l’algue artificielle (S) dans un fond marin (FM) ; - une tige (T) flexible configurée pour être repliée par des mouvements de vagues ;- des branches latérales (B) flexibles formant projections autour de la tige (T), configurées pour être repliées par des mouvements de vagues ;- un moyen de flottaison (B1) ayant une densité inférieure à celle de l’eau de mer, configuré pour maintenir la tige (T) dans une position sensiblement verticale. L’invention concerne en outre un système et un procédé de contrôle d’ensablement/érosion d’un site côtier (S1, S2) sur la base de plusieurs algues S de ce type. Figure de l’abrégé : Fig. 2The invention relates to an artificial seaweed (S) characterized in that it comprises - anchoring means (A) for anchoring the artificial seaweed (S) in a seabed (FM); - a flexible stem (T) configured to be folded by wave movements; - flexible lateral branches (B) forming projections around the stem (T), configured to be folded by wave movements; - a flotation means (B1) having a density lower than that of seawater, configured to maintain the stem (T) in a substantially vertical position. The invention further relates to a system and a method for controlling silting/erosion of a coastal site (S1, S2) based on several such seaweeds S. Abstract figure: Fig. 2
