20. ABSTRACT (Continue an reverse side If necessary and Identify by block number) 



A method is presented for the design of vertical-faced breakwaters for 

 wave transmission by overtopping based on laboratory experiments of Goda, 

 Takeda, and Moriya (1967) and Goda [1969]. A step-by-step procedure is 

 outlined, design curves are presented, and examples worked to illustrate 

 the procedure.
