Abstract: An 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 body of water such that at least a portion of the mat extends to a location 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. The stabilizers are elongated tubular elements filled with a cementitious material, and preferably a large diameter tubular element is secured between two smaller diameter tubular elements. The smaller tubular elements are filled first in order to control the position of the larger diameter tubular element during filling.

Abstract: An erosion control device for retarding shoreline erosion includes an elongated sheet with an elongated anchor extending along the elongated edges thereof to anchor the sheet to the sea bottom. A support located intermediate the elongated edges support the intermediate portions of the sheet above the sea bottom. The sheet has a plurality of openings located along the intermediate portions of the sheet to permit sand to accumulate under the sheet when the device is positioned underneath the water with the anchor anchoring the edges of the sheet to the sea bottom.

Abstract: An 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.

Abstract: A shoreline erosion control device having a base mat with a water permeable but soil retaining upper membrane secured thereto to form a plurality of forwardly opening pockets therebetween. Floatation extends along the forward edge of the upper membrane, and anchoring elements extend along substantially the entire leading edge and trailing edge of the base mat, with straps joining the upper membrane and base mat in order to limit the opening of the pockets.
