20. ABSTRACT fConffau* en rmvermm sfds If nmcrnreary and Identify by block number) 



Wave transmission and mooring-load features were tested for a floating 

 breakwater created from massive cylindrical members (steel or concrete pipes, 

 telephone poles, etc.) in a matrix of scrap truck or automobile tires. The 

 Pipe-Tire Breakwater (PT-Breakwater) was tested at prototype scale using 

 regular waves ranging in height from 0.15 to 1.78 meters and period from 2.6 

 to 8.1 seconds; water depths ranged from 2.0 to 4.6 meters. Two designs were
