Armour weight calculated using Hudson's formula for design wave height has been reduced to an extent of 20% in the present study. The variations of non-dimensional runup values (Rd/Ho) and the rundown values (Rd/Ho) with deep- water wave steepness (Ho/gT2), damage level (S) with stability number (Ns) are investigated for different depths of still water level (SWL). A decrease in runup and rundown with wave steepness has been observed. Location of berm near SWL has been found to be more effective in reducing the wave runup. Damage level increases with decrease in wave period within the limits of experimental variables studied. � 2005 Taylor & Francis Group, LLC.Article
