"Placed-stone" jetty, stone weight coefficients
Model study showed that when two layers of stones are placed with long axes perpendicular to length of jetty and tilted slightly downward toward center of rubble mound, stone-weight coefficients of 5.7 and 6.7 could be obtained with breaking waves and nonbreaking waves, respectively; coefficients compare to 2.8 and 3.5 for similarly rough stones dropped by pell-mell method; placed-stone method of jetty construction requires stone approximately one-half size required for pell-mell construction.
