WALKING SAND SNARE AND METHOD FOR BEACH RENOURISHMENT.

摘要

A beach renourishment sand snare and a method for its employment. A series of metal posts are embedded in the sand, forming a line which is approximately perpendicular to the shore. Each post has a pair of slots cut vertically down its side, with the slots being oriented in a direction which is perpendicular to the shore. Semi-rigid mesh panels are constructed of polymer coated wire mesh. Each side of the mesh panel is enclosed in a clamping assembly. Each clamping assembly is configured to slide into the slots cut into the posts, with means provided to secure the clamping assembly in place in the slot. Thus, a mesh panel may be lowered into place and secured between adjacent posts by sliding the clamping assemblies on either side of the mesh panel into the slots in the two adjacent posts. A method of applying the sand snare is also disclosed. The placement of the mesh panel in the surf tends to accumulate sand around the panel. The sand will eventually accumulate to the point that the shoreline will advance seaward of the mesh panel. Because each mesh panel is independently placed. once the shoreline has advance past its position, that panel can be removed and transferred to the seaward end of the line of posts. Likewise, the posts on the landward side can be removed and transferred to the seaward side once they are no longer needed thereby extending the line of posts. In this fashion, a series of posts and mesh panels can be "walked"into the sea, accumulating sand and advancing the shoreline indefinitely.
