Wave Attenuation Device For Restoration Of Oyster Reefs

Abstract

A wave attenuation device converts rotational wave energy of a water body into directional laminar flow. The wave attenuation device includes one or more semi-flexible panels having a second portion inclined with respect to a first portion and a third portion thereof. The semi-flexible panels are spaced apart with respect to each other in a vertical direction. The wave attenuation device includes a plurality of support pilings for supporting the one or more semi-flexible panels on a concrete bed position at a bottom of the water body. A highest point of the plurality of supports pilings is located at a mean low tide height of the water body. A space between the semi-flexible panels is open to flow of water, to enable delivery of food particles to oyster reefs located in the water body, while preventing sediment accretion.

What is claimed is: 
     
         1 . A wave attenuation device for converting rotational wave energy of a water body into directional laminar flow, the wave attenuation device comprising:
 one or more semi-flexible panels having a second portion inclined with respect to a first portion and a third portion thereof, the one or more semi-flexible panels being spaced apart with respect to each other in a vertical direction, wherein
 the one or more semi-flexible panels includes a first portion, a second portion and a third portion, 
 the second portion having a first end inclined with respect to the first portion and a second end inclined with respect to the third portion, 
 the second portion is inclined with respect to the first portion with an inclination angle ranging from 20-40°, and 
 the third portion extends from the second portion and is parallel to the first portion; and 
   a plurality of support pilings for supporting the one or more semi-flexible panels on a concrete bed position at a bottom of the water body, a highest point of the plurality of supports pilings being located at a mean low tide height of the water body.
