A mathematical model for unsteady supercritical flow on a mobile sandy bed

Supercritical flow with sediment transport is a common phenomenon in steep rivers. This kind of flow presents features not present in rivers flowing in subcritical conditions. The development of a mathematical model to simulate supercritical flow with sediment transport in sandy rivers is described....

Zusammenfassung:Supercritical flow with sediment transport is a common phenomenon in steep rivers. This kind of flow presents features not present in rivers flowing in subcritical conditions. The development of a mathematical model to simulate supercritical flow with sediment transport in sandy rivers is described. The model is based on a numerical scheme for the integral version of the full governing equations and takes into account bottom configurations.
