A method is presented to predict, approximately the velocities behind a propeller of sailing and maneuvering ships. The influences of the rudder, the rudder angle and an eventual nozzle are taken into account. Relations are also developed between the current velocities and the stability of bottom and banks consisting of non-cohesive material. With the results obtained it is possible to determine whether or not erosion will occur, to calculate the dimensions of the scour hole or to determine the required dimensions for protection materials.
