Title: Stability of Armor Units for Submerged Breakwaters by Irregular-Wave Tests
Abstract: Irregular-wave model tests of the stability of armor units for submerged breakwaters were conducted. To assess the stability of the armor units, armor units segmented with colored stripes for reference were arranged on the surface of submerged breakwaters, and the wave height was gradually increased in 2-cm increments to determine the damage ratio. The required weight for an armor unit can be obtained by Hudson's formula. The stability factor of the armor stone (specific gravity: 2.6) at a 5% damage ratio can be obtained as in fig. 8.
