Short summary
Using experiments, we found that the form and behaviour of a river depends on its ability to move the larger of its constituents. The manner in which all particles move depends upon the rate and calibre of the supplied material, as well as the rate of supplied water. This goes against the prevailing theory of a single important and representative grain size under depositing conditions, and these results may alter how we interpret river deposits to explain their formation.
