A Feasibility Study of a Wave-Powered Device for Moving Sand 

 by Fredericl< F. Monroe 



A model of a wave-powered, sand-moving device, suggested by the 

 staff of U. S. Rubber Company Research Center, was tested for feasi- 

 bi I ity as a dredg i ng device in 1 965. Tests were made at a 1:15 sea la. 

 Waves with prototype periods of 5 to 15 seconds were tested. Wave 

 heights varied from I.I to 4.4 prototype feet in prototype offshore 

 depths of 38.7, 34.5, and 30 feet. Results indicate the device, at 

 least in its present form, is unsuitable for moving sand shoreward 

 from offshore sources, and further testing in the prototype is not 

 justified. Despite disappointing results, operation of the device 

 illustrates the possibility of a great potential for utilization 

 of wave power.
