Attorney, Agent or FirmInternational ClassE02B 3/12 (20060101)AbstractAn erosion control structure and method involves placing a large permeable mat with peripheral weighted pockets around and attached to the mat on the bottom of the water body such that at least a portion of the mat extends into a shallow portion of the water body where currents have a velocity sufficient to erode the bottom. The peripheral pockets are filled with a weighted material, such as sand. Large weighted stabilizers are placed on the mat and positioned in the areas where the currents exceed the erosion velocity such that the stabilizers are below the surface of the water.Field of SearchHinged concrete sectionsMattress Continuous concrete or concrete filled bag Wave or flow dissipation BANK, SHORE, OR BED PROTECTION Revetment laying Revetment Floatable dissipator submerged at site Bed supported subsurface dissipator With fabric Associated with solid wall Spaced members Jetty Interfitted or interleaved members Openwork or concave face With anchoring of line | |
