ABSTRACT Yoo, D.H. and Lim, H.S., 2016. Erodibility assessement of Armour Blocks causing Damage to Breakwaters. In: Vila-Concejo, A.; Bruce, E.; Kennedy, D.M., and McCarroll, R.J. (eds.), Proceedings of the 14th International Coastal Symposium (Sydney, Australia). Journal of Coastal Research, Special Issue, No. 75, pp. 1272 - 1276. Coconut Creek (Florida), ISSN 0749-0208. Empirical equations such as the Hudson, van der Meer-de Jong, and Yoo equations were compared for estimating the armour block weight of the breakwater by introducing an incremental factor based on the Hudson equation. The equation for deriving the critical wave height of erosion at the structure toe was developed for additional consideration of the armour-blocked breakwater stability. All empirical equations were reformed according to the Hudson equation, which has been widely employed in engineering design, and an incremental factor was added to each reformed empirical equation. This factor reflects the characteristics of each empirical...
