A weakly non-hydrostatic shallow model for dry granular flows
José Garres-Díaz, Enrique D. Fernández-Nieto, Anne Mangeney +1
A non-hydrostatic depth-averaged model for dry granular flows is proposed, taking into account vertical acceleration. A variable friction coefficient based on the rheology i…
Multilayer models for shallow two-phase debris flows with dilatancy effects
José Garres-Díaz, François Bouchut, Enrique D. Fernández-Nieto +2
We present here a multilayer model for shallow grain-fluid mixtures with dilatancy effects. It can be seen as a generalization of the depth-averaged model presented in Bouchut et a…
Formal deduction of the Saint-Venant-Exner model including arbitrarily sloping sediment beds and associated energy
E. D. Fernández-Nieto, T. Morales de Luna, G. Narbona-Reina +1
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 t…
