A novel fully conservative model for sediment transport and bed evolution in river flow has been derived by a two-phase approach. Referring to a two-dimensional depth-averaged framework, two scalar mass conservation equations and two vectorial momentum conservation equations are written for water and sediment separately, and cuopled with bottom evolution equation due to erosion/deposition. Sediment inertia, momentum exchanged between phases by drag forces an tangential stresses opposing motion are taken into account in a fully coupled formulation for solid transport under non-stationary conditions.
