Abstract : This report describes a two dimensional physical model investigation of the Ofu breakwater, American Sarnoa. Two-dimensional wave tests were conducted to determine the stability of selected concrete armor units when placed on concrete revetment blocks and subjected to a design condition of a 17-sec, 3A7-m (11 .4-ft) wave. A proposed breakwater consisted of 4.1-tonne (4.5-U.S.-ton) tribar armor units, placed on an underlayer of lAS-tonne (l.6-U.S.-ton) 30-percent porosity blocks, secured at the crown transition with a concrete rib cap. Testing indicated that units will remain hydraulically stable for the specified design wave condition.
