A semi-implicit approach for sediment transport models with gravitational effects
(Elsevier, 2022)
In this work efficient semi-implicit methods for sediment bedload transport models with gravitational effects under subcritical regimes is proposed. Several families of models with gravitational effects are presented and ...

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 ...
