PREFACE 



This report describes a brief series of prototype scale tests of a 

 floating tire breakwater system that uses the Goodyear Tire and Rubber 

 Co. tire module arrangement. The report is published to provide coastal 

 engineers with information on the mooring load and wave transmission 

 characteristics of the floating tire breakwater system for a range of 

 incident wave conditions at two water depths. The research was carried 

 out under the structure-sediment-hydraulic interaction research program 

 of the U.S. Army Coastal Engineering Research Center (CERC) . 



The report was prepared by Michael L. Giles and Robert M. Sorensen, 

 Coastal Structures Branch, Research Division, CERC, under the general 

 supervision of R.P. Savage, Chief, Research Division. 



The tests were conducted jointly by CERC and the Lake Erie Marine 

 Science Center (LEMSC) in the CERC large wave tank. The LEMSC provided 

 the tire breakwater and the mooring system. The load cells used to 

 measure the mooring loads were provided by the Lord Corporation, Erie, 

 Pennsylvania, through the LEMSC. Dr. R. Pierce and several students 

 from the LEMSC actively participated in setting lip and conducting the 

 wave tank tests. M.L. Giles, the CERC project engineer for the tests, 

 was also assisted by F.L. Lago and L. Meyerle.
