Modelling of bedload sediment transport for weak and strong regimes
(Springer, 2021)
A two-layer shallow water type model is proposed to describe bedload sediment transport for strong and weak interactions between the fluid and the sediment. The key point falls into the definition of the friction law between ...

Non-hydrostatic layer-averaged approximation of Euler system with enhanced dispersion properties
(Springer, 2023-05-10)
A new family of non-hydrostatic layer-averaged models for the non-stationary Euler equations is presented in this work, with improved dispersion relations. They are a generalisation of the layer-averaged models introduced ...

Multilayer models for hydrostatic Herschel-Bulkley viscoplastic flows
(Elsevier, 2023-06-01)
Starting from Navier-Stokes’ equation we derive two shallow water multilayer models for yield stress fluids, depending on the asymptotic analysis. One of them takes into account the normal stress contributions, making ...

Numerical simulations of a dispersive model approximating free-surface Euler equations
(Springer, 2021-10-18)
In some configurations, dispersion effects must be taken into account to improve the simulation of complex fluid flows. A family of free-surface dispersive models has been derived in Fernández-Nieto et al. (Commun Math Sci ...

Performance and limits of a shallow-water model for landslide-generated tsunamis: from laboratory experiments to simulations of flank collapses at Montagne Pelée (Martinique)
(Oxford University Press, 2023-05)
We investigate the dynamics and deposits of granular flows and the amplitude of landslide-generated water waves using the HySEA depth-averaged shallow-water numerical model, both at laboratory and field scales. We evaluate ...
