Abstract

Time evolution of scoured seabed profiles around a vertical slender cylinder under waves has been investigated by means of laboratory experiments. The characteristics of the scoured bed profiles on the developing process is discussed considering the flow features. The local scoured bed profiles are classified with the location of the maximum scoured point. And the developing scouring process of each classified type is discussed. We found that for each scour type, the scoured bed retains a similar profile during its whole developing process. The ultimate scour depth on the vicinity of the cylinder surface is related to the Keulegan-Carpenter number, and it is independent of the sand bed condition.
