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, are 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. Further, a crossing tubular element is preferably positioned across a shoreward end of the elongated tubular element in order to form a barrier against wave movement around and past the shoreward end of the elongated tubular stabilizer.
