Abstract: The statistical properties of the downstream propagation speed of the alluvial bedforms and the associated progression speeds of the individual sediments were evaluated on the basis of a series of radio-active tracer sxperiments conducted in a laboratory flume over a fairly broad range of flow conditions in which dunes were observed. The probability density functions for the progression speeds of the sediment motion were derived and found to fit well with the tracer results.
