SPEED OF INERTIAL BED LOAD DISTURBANCES

The flow of water on a movable bed is studied by the method of characteristics. The equations of motion and continuity for water and bed load are considered separately. A relation between the velocity of propagation of a slight disturbance in the rate of bed load transport and the average bed load velocity is obtained. Also the possibility of the existence of more than one velocity of propagation for "bed forms" or disturbances in the static bed level, is indicated. A method of approximate numerical solution of the flow equations is given. /Author/
