Abstract : Laboratory investigations were recently conducted at the U.S. Army Engineer Waterways Experiment Station (WES) Coastal and Hydraulics Laboratory (CHL) to improve design criteria for selectively placed armor stone on coastal structures to reduce the cost of future construction. Present field practice is to place quarrystone armor units to provide the best fit obtainable for particular site conditions. The selective placement of quarrystones one at a time to achieve the best fit, often called standard placement, is known to provide better stability and a tighter interlocking of the armor stones (Camfield 1996a). The tighter fit of armor stones using this placement method may allow the use of a single layer of armor stones.
