Abstract

The three components of the pebble clusters occurring on the surface of a gravel bar were painted using different colours. Before and after each flood all the clusters were photographed and a comparison was made. This simple methodology allowed the evolution of the painted clusters to be followed and also allowed a survey of the dislodgment of the clusters particles and the addition of new ones. The experiment shows that the mobility of the wake grains is higher than that of the stoss particles. A pebble cluster generally loses the wake grain first, followed by the stoss pebbles. Discussion
