The effect of river dunes on the morphodynamic response to overloading

A new two-layer model for conservation of mixed sediment for bedform-dominated condi-tions is proposed. There is a need for such a new bedlayer-type sediment conservation model, as (i) the commonly applied Hirano (1971) model does not account for the effects of bedform stochastics and ver-tical sorting on bed level changes, (ii) the Ribberink...
