Abstract
An apparatus and method for reducing the strength of the nearbottom offsh directed current inside the surfzone thereby promoting and sand accretion on the beach. An arrangement of pipes is placed in the surfzone and operates to sequester a portion of surfzone fluid. The sequestered surfzone fluid is conveyed out to sea by way of the piping system thereby reducing the velocity and quantity of surfzone fluid reducing sand erosion.
Claims10
An apparatus for artificially reducing the strength of the nearbottom offshore directed current inside a surfzone thereby promoting sand accretion on a beach comprising:
- (a) means located in the surfzone for sequestering a portion of surfzone fluid;
- (b) discharge openings located beyond said surfzone for allowing the discharge of the sequestered surfzone fluid to open sea;
- and
- (c) conveying means communicating with the sequestering means on one end and with the discharge openings on the other end, the conveying means operating to guide said sequestered surfzone fluid from said sequestering means to said discharge openings.
A method for artificially reducing the strength of the nearbottom offshore directed current inside a surfzone thereby promoting sand accretion on the beach, said method comprising:
- (a) sequestering a portion of surfzone fluid inside the surfzone;
- then
- (b) conveying the sequestered surfzone fluid to a discharge point beyond said surfzone;
- then
- (c) discharging said sequestered surfzone fluid into the open sea at the discharge point.
