Abstract: The rubble-mound breakwaters are suitable for nearly all types of foundations and any economically acceptable water depth. They have the longest construction history among various types of breakwaters and have been most widely used in the Republic of Korea. However some serious damages for the rubble-mound breakwaters are reported frequently and the damages are concentrated on the head parts of breakwaters. A series of stability tests for the rubble-mound breakwaters has been carried out in an elaborately controlled laboratory facility. The basin is 42m long and 36m wide. A uni- directional spectral wave generator is installed in one end of the basin and is used to generate irregular waves with equivalent significant wave heights and wave periods. The stability of breakwaters is investigated in detail for changes of wave heights, wave periods and incident angles of waves.
