Description :
This paper confirms the presence of large-scale flow structures in gravel bed rivers, pictures their sequence and patterns and characterises their mean and individual properties. The analysis relies on a new technique for displaying velocity fluctuations in a space-time matrix that allows one to see the structures as they pass an array of current meters. Because of their duration and size, the high-speed wedges are likely to play a major role in sediment transport.
