20. ABSTRACT fConffinue oa raveram ah£a ff naiceaaary mid Identity by block number) 



Methods are presented for estimating coefficients of wave transmission by 

 overtopping for smooth and rough impermeable breakwaters. These techniques can 

 be used for monochromatic or irregular wave conditions and for submerged break- 

 waters. Example problems are worked to illustrate calculations.
