The characteristics are examined of the sea bed erosion produced by the scouring action of a ship's propeller wash acting against a quay wall. The rate of development of erosion by a confined propeller jet is either greater or less than that produced on a semi-infinite bed. The magnitude of scour has been found to be dependent on the location of the quay wall relative to the propeller. Equations have been proposed to estimate the maximum extent of the erosion.
