  • The dominance of dispersion in the evolution of bed material waves in gravel-bed rivers
  • This paper summarizes recent theoretical models, experiments and field studies that have been designed specifically to measure relative rates of dispersion and translation of bed material waves. In considering uniform channels only, and also
  • in disregarding exchanges of sediment between a channel and its floodplain, 2 factors influence wave behaviour : interactions between flow, wave topography and bed load transport; and relative particle sizes of input sediment and pre-existing bed material
  • . The results indicate that dispersion dominates the evolution of bed material waves in gravel-bed channels.
  • Determination of the sediment transport in an armoured gravel-bed river
  • -discharge (Qb/Q) relationships are determined by local bed-load transport in the Common Meuse. The survey data in the Common Meuse were analysed with a geographical information system (GIS) (ARC-INFO) to produce maps of the river-bed level. The subtraction
  • of maps of bed levels in different years results in a map with spatial distributions of erosion and sedimentation.
  • Bed configuration and microscale processes in alluvial channels
  • The research questions discussed in this article are central to the understanding of fluvial processes in both sand- and gravel-bedded rivers. Prominent research themes are identified. The first is the use of fractal concepts in the study of fluvial
  • processes. The second is the study of turbulent flow structures. Finally, this review clearly focused on bed microtopography and related flow turbulence and sediment transport processes.

  • This paper examines the effects of base level lowering on the channel morphology of the southern end of the Lower Jordan River. The recent chronology and rate of channel changes through the lower reach of the river caused by the lowering of the base
  • Toward a practical method for estimating sediment-transport rates in gravel-bed rivers
  • sedimentology of anastomosed and wandering gravel-bed rivers. The scale problems of facies analysis may be overcome by employing architectural element analysis in conjunction with modern geophysical methods such as shallow reflection seismology and ground
  • Canadian river scientists made significant contributions to the early development (1960-80) of fluvial facies models, particularly to those for braided rivers. More recent Canadian studies (1980-92) have centred on understanding the facies
