Abstract: The propeller generates a turbulent jet that impacts the seabed or the bottom of a navigation channel, reaching a considerable distance from the propeller itself. The presence of a boundary has a significant impact on the propeller jet development. Tsinker (2012) emphasized the need to consider propeller-induced scour during the design of new port-related structures or when reassessing the performance of existing structures. He noted that all the types of structures could potentially experience scour caused by propellers, especially those designed to withstand horizontal and vertical loads as closed vertical quays and the scour associated with them is generally confined to the area in front of the berth front wall. The still water condition, common in technical literature, is not representative of mooring in navigable channels where a channel flow can influence the scour induced by a propeller jet. In the present work, the scouring process, laterally confined by a quay wall, and induced by the combined effects of the propeller rotation and a water flow running in a laboratory flume was investigated.
