Short summary

This study tracked the episodic motion of coarse sediment cobbles over 2 years to unravel how floods in mountain rivers move sediment. Despite large fluctuations in river discharge and natural variability in climate and topography, observed sediment dynamics agree well with theory and small-scale laboratory experiments; results demonstrate that sediment particle motion can be predicted from a record of river flow depth, providing a direct link between climate and sediment transport.
