Beach erosion mitigation device

摘要

A beach erosion mitigation device is provided that includes an elongated, tubular member configured to be tethered to the shoreline and attenuate wave energy. The tubular member comprises a corrugated construction having enclosed air pockets that afford buoyancy. The ends of the tubular member are open, while along its length are disposed a set of overflow openings and a set of venturi openings. The venturi openings receive incoming water from the breaking wave and direct it axially along the interior of the tubular member. The overflow openings and the open ends allow water to escape prior to the next wave arrival. The device is placed alone, or in groups, along a shorefront to directly receive the energy of breaking waves. The energy thereof is attenuated by the structure of the device and via its redirection therethrough, thereby combating beach erosion caused by storm swells and high energy waves.

主权项

1. A beach erosion mitigation device, comprising:
an elongated tubular member having a rounded sidewall, a length, an open interior, and a pair of open ends; said rounded sidewall having an enclosed volume of air therein such that said tubular member is buoyant; a first set of openings through said sidewall comprising one or more overflow openings; a second set of openings through said sidewall comprising one or more venturi openings; each of said venturi openings comprising a tapering opening with a frontal portion, a rear portion, and an opening edge; said frontal portion being wider than said rear portion, and said opening edge tapering between said frontal portion and said rear portion.
