Abstract
Wave induced scouring around a large-scale offshore structure is investigated by a series of model experiments. Scour patterns are compared and classified for various shapes and types of structures, and with those in front of breakwaters. The influence of the structure's being submerged and the foundation's being not embedded also examined. Scour and accretion at the side of a cylinder is related to the gradient of the velocity amplitude caused by waves. The relationship between maximum scour depths and the incident wave height are obtained.
