A Weakly Non-hydrostatic Shallow Model for Dry Granular Flows
(Springer, 2021)
A non-hydrostatic depth-averaged model for dry granular flows is proposed, taking into account vertical acceleration. A variable friction coefficient based on the μ(I) rheology is considered. The model is obtained from ...

A bed pressure correction of the friction term for depth-averaged granular flow models
(Elsevier, 2022)
Depth-averaged models, such as the Savage-Hutter model with Coulomb or Pouliquen fric tion laws, do not in some cases preserve the physical threshold of motion. In particular, the simulated granular mass can start to flow ...
