Abstract: The purpose of the present paper is to provide a practical approach by which the random wave-induced scour characteristics around submerged breakwaters can be derived. First, the two-dimensional onshore scour along the base of submerged vertical and semicircular breakwaters exposed to normally incident random waves on both sloping and horizontal sandy bottom is given, by using the regular wave formulas by Young and Testik (2009). The scour characteristics considered are the maximum scour depth, the scour length, and the distance of the maximum scour depth location from the onshore breakwater face. Second, the two-dimensional maximum scour depth in the offshore front of a submerged vertical breakwater exposed to normally incident random waves on a horizontal sandy bottom is given, by using the regular wave formula by Lee and Mizutani (2008). The wave motion is assumed to be a stationary Gaussian narrow-band random process.
