Grain size, sediment transport and alluvial channel pattern

Authors(s) and Affiliation(s)



The Shields parameter, a dimensionless bed shear stress which can be expressed as a ratio of the slope, depth and characteristic properties of bed material in an alluvial channel, has been observed in natural rivers to take on modal values for the regime of bedload, mixed-load and suspension transport. The conditions correspond to channel geometries associated with conserved sediment flux. These findings are extended here to accommodate the effects of channel width in the context of a comprehensive data set on stable, perennial rivers. This new analysis reconcilies existing empirical and theoretical approaches to predict alluvial geometry
