Abstract

After a quick overview of recent research on sediment transport by shear flow and ripple and dune formation, original numerical results are presented from two-phase flow modelling of the interaction between a viscous flow and a bed of particles. Good agreement is found with previous experiments or numerical simulation, notably for the particle flux and velocity profiles within the moving layer. Bed instability is also found, giving rise to ripples whose characteristics are discussed.
