Myrhaug, D., & Ong, M. C. (2020). Assessment of Shallow Water Random Wave-Induced Scour at the Trunk Section of Breakwaters using Deep Water Wind and Wave Conditions. Journal of Coastal Research, 95(SI), 289-293. 10.2112/SI95-056.1Sammendrag
This article provides a simple analytical method giving estimates of random wave-induced scour at the trunk section of vertical-wall and rubble-mound breakwaters in shallow water from deep water wind and wave conditions. Results are exemplified by using a Pierson-Moskowitz model wave spectrum for deep water wind waves with the mean wind speed at the 10 m elevation above the sea surface as the parameter. The significant value of the scour depth within a sea state of random waves is provided and an example typical for field conditions is given. The method should serve as a useful tool for assessing shallow water random wave-induced scour based on input from deep water wind and wave conditions.
