Abstract: The purpose of the investigation herein was to obtain design information for stone and dolos armor used on breakwater heads and subjected to nonbreaking waves. More specifically, it was desired to determine the minimum weight of individual armor units (with given specific weights) required for stability as a function of: (a.) Type of armor unit. (b.) Sea-side slope of the structure. (c.) Angle of wave attack. (d.) Wave period. (e.) Wave height. Based on tests and results described herein, in which stone and dolos armor are used on conical breakwater heads and subjected to nonbreaking waves with angles of wave attack of 0, 45, 90, and 135 deg, it is concluded that: (a.) The longer wave periods (2.00 and 2.75 sec) generally produce the lower stabilities. (b.) Angles of wave attack of 45 and 90 deg are the most critical. (c.) Flattening the slope from 1V on 1.5H to 1V on 2H does not improve stability of the stone armor.
