20.- ABSTRACT (Caatbua an ravaraa afate ff iiataaaaiy aad tdatttlty by block numbar) 



The results of previous tests of monochromatic wave runup on both smooth 

 and rough slopes were reanalyzed. A method is presented for estimating wave 

 runup on coastal structures with rough surfaces. This method is an extension 

 of procedures described in the Shore Protection Manual (SPM)(U.S. Army, Corps 

 of Engineers, Coastal Engineering Research Center, 1977). Where data were 

 not presently available, the method uses the wave runup on smooth slopes and 

 then adjusts the value by a rough-slope runup correction factor to determine
