This paper provides a stochastic method by which the two-dimensional onshore scour characteristics along the base of submerged breakwaters exposed to normally incident random waves on a mildly sloped sandy seabed can be derived. Here the formulas for the regular wave-induced scour characteristics provided by Young and Testik (2009) combined with the Battjes and Groenendijk (2000) wave height distribution for mild slopes are used. These formulas are combined with describing the waves as a stationary random process. An example is included to calculate the significant values of the random wave-induced onshore scour characteristics; the maximum scour depth, the scour length, and the distance of the maximum scour depth location from the onshore breakwater face. The present results can be used to make assessment of the random wave-induced scour characteristics based on available wave statistics.
