Abstract:
The causes of bed instability in a sandy bed channel are analyzed using a formula of sediment transport rate containing no phenomenological parameters. The sediment transport rate is uniquely determined by the normal and shear stresses on the bed and the slope of the bed surface. Using a linear model, it is shown that the only factor responsible for bed instability is perturbations of the normal bed pressure regardless of their nature.
Keywords:
channel processes, transported sediments, bed layer, bottom waves, bed instability.
