Particle clusters in gravel-bed rivers : an experimental morphological approach to bed material transport and stability concepts

Auteurs :

Description :
This study takes a morphological approach to interpreting the critical processes, using particle tracing to determine the movement of individual cluster particles over a range of flood event magnitudes and durations. The experiment was carried out on the River South Tyne, UK; it uses flow hydrographs measured nearby and also benefits from previous studies of historical development, channel morphology and sediment transport at the same site. More than 30 clusters were monitored over a seven-month period. Threshold flows delimiting 3 apparently contrasting bed sediment process regimes for cluster particles are tentatively set.
