The inner width of the transparent cylinder of the flume is 10 cm, and the height is 25-50 cm. The desired speed of the circular flow can be set by pumping the water into the channel in a tangential direction from a tank in the bottom of the machine. It is expected that the device will be suitable for laboratory experiments 
simulating the rather complicated behaviour of sediment particles in a river bed, thereby helping to gain a deeper understanding of the shape evolution of pebbles exposed to friction and collision.
