2Q* ABSTRACT (Canttnum am rerermm sfofi> ff nac ea aa ry and. Identity by block number) 



Floating tire breakwaters (FTB) are being used to protect and improve small- 

 craft harbors, and as the need for additional mooring space increases, FTB's are 

 often being placed in locations exposed to larger waves. Other uses for FTB's 

 include protection of construction operations, protection of dredges, and beach 

 stabilization. Methods for predicting the transmitted wave height, as well as 

 for determining the anchor loading for the Goodyear module FTB, are presented.
