Although studies of sediment transport in steep and coarse-grained channels have been more numerous in recent years, the dynamics of sediment transport in step–pool river systems remain poorly understood. This paper investigates displacements of in

In gravel-bed rivers, bed sedimentary structures exert a significant influence on the stability of the bed, particle motion and stream dynamics. A detailed description of the development of sedimentary structures is essential to define the overall ac

In gravel-bed rivers, measuring the displacement of individual grains by fluid flow is essential in order to understand sediment transport processes and to investigate changes in channel morphology. We present preliminary results of a new technique t

In gravel-bed rivers, bed roughness is often controlled by the spatial distribution of pebble clusters and large protuberant clasts. The turbulent flow structure around these roughness elements has been studied extensively as opposed to the effects o

In this paper, we present a detailed investigation of the size, scale and dynamics of macro-turbulent flow structures in gravel-bed rivers. We used an array of seven electromagnetic current meters with high resolution in both space and time to measur

Dans les cours d’eau à lit de graviers, les blocs et les amas de galets entraînent des changements de rugosité qui jouent un rôle important sur la variabilité spatiale du cisaillement exercé sur le lit, de la structure de l’écoulement et d
