Description:	Miscellaneous Paper Abstract: Model tests were conducted on STA-POD armor units used on selected groin-type structures, subjected to the largest waves that can attack the units when placed in the surf zone in a water depth equal to the height of the unit. One preliminary test also was conducted to obtain an indication of the stability of STA-PODS when used on a breakwater slope (1:1.5). All tests were conducted in a wave flume 110 ft long, 4 ft wide, and 4 ft deep. The surf zone tests utilized a 1:25 model to prototype scale, while the breakwater slope tests used only model values. It was concluded from results of the surf zone tests, where the model STA-PODS were tested on a hard-surface slope, that 5-ton STA-PODS used as a groin or small jetty type structure in the prototype would be stable for wave heights in excess of the 7.5 ft tested on the model. A small area of STA-PODS tested on a 1:1.5 breakwater slope indicated that random-placed STA-PODS interlocked and provided good stability characteristics. The use of STA-PODS as a breakwater unit would be practical, provided their structural stamina were sufficient to endure forces during prototype construction and storm action, and provided additional research indicated their damage coefficient was sufficiently large to make STA-PODS economically feasible.
