Formal deduction of the saint-venant–exner model including arbitrarily sloping sediment beds and associated energy
(Dunod, 2017)
In this work we present a deduction of the Saint-Venant–Exner model through an asymptotic analysis of the Navier–Stokes equations. A multi-scale analysis is performed in order to take into account that the velocity of the ...

A two-layer shallow water model for bedload sediment transport: convergence to Saint-Venant-Exner model
(Cornell University, 2017)
A two-layer shallow water type model is proposed to describe bedload sediment transport. The upper layer is lled by water and the lower one by sediment. The key point falls on the de nition of the friction laws between ...

A multilayer shallow water system for polydisperse sedimentation
(Elsevier, 2013)
This work considers the flow of a fluid containing one disperse substance consisting of small particles that belong to different species differing in size and density. The flow is modelled by combining a multilayer shallow ...
