ABSTRACT:
An artificial seaweed device for submersion in a volume of water along a coastline for inhibiting coastal erosion and enhancing accretion of waterborne particulate matter. The artificial seaweed device includes elongate and flexible first and second anchor members each with an open inner volume for containing a volume of particulate anchoring material such as washed stone. The first and second anchor members, which may have oval or eye-shaped cross sections when filled with particulate anchoring material, are coupled together longitudinally to form a bipartite anchor unit with a bipartite anchor unit base width. A plurality of elongate and flexible artificial seaweed strips each have a fixed end attached to the bipartite anchor unit and a free end distal to the bipartite anchor unit. A space between adjacent artificial seaweed strips prevents entanglement. Tabs of buoyant material such as foamed ionomer resin are affixed to the free end of each of the artificial seaweed strips.
