ABSTRACT:
Synthetic seaweed for use in inhibiting coastal erosion comprises an elongate anchor with strips of flexible non-woven material connected to the anchor. The strips may be buoyant with or without tabs of closed cell, low density foam affixed to the free end portions thereof to enhance the buoyancy of the strips whereby they maintain a generally upright position under water. Also, the strips are treated to inhibit or prevent marine growth from forming on the surface of the strips. Such treatment may include an antifouling agent or a smooth film, applied to the strips as a laminate or extruded directly onto the strips, for example. In use, the anchor rests upon the bottom of the sea and the submerged flexible strips of non-woven material extend upwardly therefrom. The strips sway in the ocean water thereby reducing currents in the surrounding water which permits accretion of suspended sand and promotes sedimentation of solid particles.
