Shoreline Stabilization System and Method

Abstract

A shoreline stabilization system and method are provided, comprising one or more base layers of a non-woven plastic matrix positioned on a shoreline, wherein the base layer is at least partially submerged in the water. A second layer of non-woven plastic matrix positioned on top of the base layer, wherein the second layer is at least partially submerged in the water, and wherein the second layer is pre-planted with one or more selected plants such as smooth cord grass (Spartina alterniflora), seashore paspalum (Paspalum vaginatum), torpedo grass (Panicum repens), and / or bull rush (genus Scirpus). Other selected plants are inserted into holes in the base layer such as bunchgrass, tussock, and / or sunshine vetivergrass (Chrysopgon zizanioides). The base layer and the second layer are anchored to the shoreline by a plurality of anchors sufficient to cause the base layer to conform to the shoreline. The assembled system provides protection from wave energies, while allowing for plant and root growth to further reinforce the shoreline.

AI Technical Summary

Benefits of technology

The present invention provides a shoreline stabilization system and method using a non-woven plastic matrix containing selected plants that can grow into the matrix and anchor the system to the shoreline. The system includes a base layer that is at least partially submerged in water and a second layer that is pre-planted with the selected plants. The selected plants have rooting and propagation characteristics sufficient to establish growth in the matrix and towards the water. The base layer and the second layer are anchored to the shoreline by a plurality of anchors sufficient to cause the anchor to conform to the shoreline. The non-woven plastic matrix is a recycled polyethylene terephthalate plastic containing no phenol-formaldehyde resins. The selected plants in the second layer include smooth cord grass, seashore paspalum, torpedo grass, bull rush, and their variants. The base layer and second layer are positioned at least partially overlapping and can be progressively positioned towards the water. The shoreline is shaped and graded prior to installation of the base layer. The system uses an anchor plate with a plurality of holes and an elongated reinforcement bar staple inserted through the anchor plate and driven into the shoreline.

Problems solved by technology

Erosion of coastal areas and shorelines due to erosion, either through natural effects or caused by human activities, is a serious problem for many areas around the world.

Natural occurrences such as waves, hurricanes, and floods may destroy ecosystems, as well as wave action attributable to boat traffic and other vehicles.

However, the conditions, both naturally occurring and man-made, that are impacting the Louisiana coastline and similar regions do not allow for this spontaneous recovery.
