Seven series of tests were conducted on 147.6- and 158.6-scale models of rubble-mound breakwater sections constructed of quarrystone and tetrapod armor units to obtain data from which competitive designs could be developed for construction of a breakwater at Tsoying Harbor. The plan tentatively selected for construction involved a cover layer comprising two layers of pell-mell placed tetrapods, and incorporating berms because of unstable prototype foundation conditions. The model tests of this design showed that a The breakwater head is nearly adequate to withstand the 27-ft prototype design wave. Some damage to the head may be expected from near the crown to the elevation of the lower berm however, the stability of the head will probably not be endangered. b The trunk will withstand the attack of 28-ft waves. c The crown elevation is not sufficient to prevent overtopping by the 27-ft design wave, but neither the crown nor the channel side of the trunk would be appreciably damaged by overtopping.
