Abstract: In conventional two-layer systems various armor units such as tetrapod, dolos, and tribar have been commonly used. Recent developments are accropode and core-loc^{TM}, which can be used in a single layer of armoring. The units for one-layer systems have an interlocking response under waves and hence their stability is high. The structure slope, wave conditions and placement methods are other areas of interest related to the stability of breakwater armor units. This study was intended to investigate the stability of core-loc^{TM} units over a 1:1.5 slope under non-breaking / breaking and regular/random wave conditions and also to compare two different placement methods of core-loc^{TM} as they affect breakwater stability. The results are also reviewed in comparison with previous studies of one-layer breakwater stability. In addition, run-up and run-down on core-loc^{TM} armor layers were also investigated.
