Abstract: The system utilizes a matrix of inflation modules held in position by x-y orthogonal cables. The inflation modules contain hydroscopic materials such as polymer power that swells when wet to produce modules of substantial height. The modules may be stacked in rows and columns to bridge a gap in a levee. Ballast holds the bottom of the matrix down and inflation modules, which may be air filed spheres hold the top of the matrix, on or near the surface of the water. The matrix may be configured to have a levee side that is as narrow as the opening in the levee and a water side that is wider than the gap in the levee to produce a wedging effect. Orthogonally arranged cables maintain the inflation modules in position and are used to anchor the matrix to intact portions of the levee. At points where the cables intersect they are held together by connector modules which a comprised of two halves with groves for cables and provision for holding the halves together with a bolts or other fasteners.
