  • Viscous drag and non-laminar flow component of underwater erosion control system
    Patent number: 5871303
    Abstract: An underwater erosion control system (10, 110) has an array of panels of material (12, 112). Each generally rectangular panel of material has a retaining portion (20, 120) and at least one sheet (16, 116). Each sheet contains a plurality of slits, (22, 122) which are generally perpendicular to the retaining portion (20, 120). The slitted sheets disrupt laminar flow in the vicinity of the erosion control system and promote rapid precipitation of particulates out of suspension. The slits (22, 122) begin at the retaining portion and terminate at the top edge (18, 118) of the sheet. The retaining portion (20, 120) may contain openings (26, 126) sized to receive an anchor component (28) that is anchored to the sea or river bed. The panel of material (12, 112) is durable and buoyant having a polymer backing (40) laminated to a closed cell polymer foam (42).
