| Description: | Technical Report Abstract: This report describes a two-dimensional physical model investigation of the Ofu breakwater, American Samoa. 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, 3.47-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 1.45-tonne (1.6-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. |
