A FEASIBILITY STUDY OF A WAVE-POWERED DEVICE FOR MOVING SAND

A MODEL OF A WAVE-POWERED, SAND-MOVING DEVICE, SUGGESTED BY THE STAFF OF THE U.S. RUBBER COMPANY RESEARCH CENTER, WAS TESTED FOR ITS FEASIBILITY AS A DREDGING DEVICE EARLY IN 1965 AT THE U.S. ARMY COASTAL ENGINEERING RESEARCH CENTER. SIXTEEN TESTS WERE MADE UNDER VARIOUS WAVE CONDITIONS AT A 1:15 SCALE REDUCTION. IN HALF OF THE SIXTEEN RUNS, MORE SEDIMENT WAS ACCRETED LANDWARD OF THE DREDGE THAN WAS ERODED AND DEPOSITED SEAWARD OF IT. YET, IN ONLY TWO OF THESE TESTS WAS THE SHOREWARD ACCRETION SIGNIFICANT. OF THE EIGHT TESTS THAT RESULTED IN EROSION ON THE SHOREWARD SIDE OF THE DEVICE, FIVE SHOWED SIGNIFICANT AMOUNTS. ACCRETION LANDWARD OCCURRED WHEN THE DREDGE WAS OPERATED IN SHALLOW WATER OVER A NEARLY HORIZONTAL BOTTOM. OVER A SLOPING BOTTOM, THE DREDGE SERVED GENERALLY TO ERODE MATERIAL AND DEPOSIT IT DOWNSLOPE. THESE RESULTS INDICATE THAT THE DEVICE, AT LEAST IN ITS PRESENT FORM, IS UNSUITABLE FOR USE IN MOVING SAND SHOREWARD FROM OFFSHORE SOURCES, AND THAT FURTHER TESTING IN THE PROTOTYPE IS NOT JUSTIFIED. DESPITE THE DISAPPOINTING RESULTS, THE OPERATION OF THE DEVICE ILLUSTRATES THE POSSIBILITY OF A GREAT POTENTIAL FOR THE UTILIZATION OF WAVE POWER. /AUTHOR/
