19 ABSTRACT (Continue on reverse if necessary and identify by block number) 



Laboratory tests to determine irregular wave overtopping rates on coastal structures 

 were conducted at the Coastal Engineering Research Center in Vicksburg, Mississippi. These 

 tests were intended to solve a site-specific problem at Roughans Point, Massachusetts. The 

 results have yielded specific information for Roughans Point and a general approach to 

 calculating irregular wave overtopping rates which is superior to the method given in the 

 Shore Protection Manual ( 1 984 ) .
