ABSTRACT:
A shoreline erosion-reversing system and method provides seawards and landwards "quiet" zones which cooperate to promote landwards soil deposition and to mitigate seawards soil scouring. In accord therewith, a series of one or more upstanding, vertically-movable and negatively-buoyant apertured sections are arrayed on a shoreline to be protected. Each section is comprised by a hydrodynamic fence subassembly having a lattice of slats fastened in spaced-apart relation to top and bottom horizontal support members and by a pile subassembly having at least one pile member, which subassemblies cooperate to allow the hydrodynamic fence subassembly to move in a binding-free manner relative to the pile subassembly. The top and bottom horizontal members may be singly and/or doubly arranged and may be implemented with either flexible or rigid members. The slats of the lattice of slats may be singly, doubly and/or triply arranged. End assemblies are disclosed for terminating flexible horizontal support members. Upstanding, vertically-movable negatively- and positively-buoyant apertured sections may be arrayed back-to-back to eliminate overtopping. Sections may be selectably arrayed to prevent flow-around, provide beach access, and, among other things, to go round not easily removable beach objects.
