A general vertical decomposition of Euler equations: Multilayer-moment models
(Elsevier, 2023-01)
In this work, we present a general framework for vertical discretizations of Euler equations. It generalizes the usual moment and multilayer models and allows to obtain a family of multilayer-moment models. It considers a ...

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 ...

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 ...
