A consistent intermediate wave speed for a well-balanced HLLC solver.
(Gauthier-Villars, 2008)
In this work, we present a HLLC scheme modification for application to nonhomogeneous shallow-water equations with pollutant transport. This new version is related to the definition of a consistent approximation of the ...

On a shallow water model for the simulation of turbidity currents
(Cambridge University Press, 2009)
We present a model for hyperpycnal plumes or turbidity currents that takes into account the interaction between the turbidity current and the bottom, considering deposition and erosion effects as well as solid transport ...

Multilayer shallow water models with locally variable number of layers and semi-implicit time discretization
(Elsevier Inc., 2018)
We propose an extension of the discretization approaches for multilayer shallow water models, aimed at making them more flexible and efficient for realistic applications to coastal flows. A novel discretization approach ...

Layer-averaged approximation of Navier-Stokes system with complex rheologies
(EDP Sciences / Société de Mathématiques Appliquées et Industrielles, 2023)
In this work, we present a family of layer-averaged models for the Navier–Stokes equations. For its derivation, we consider a layerwise linear vertical profile for the horizontal velocity component. As a particular case, ...

Sediment transport models in Shallow Water equations and numerical approach by high order finite volume methods.
(Elsevier, 2008)
This paper is concerned with the numerical approximation of bedload sediment transport due to water evolution. For the hydrodynamical component we consider Shallow Water equations. The morphodynamical component is defined ...

Derivation of a Multilayer Approach to Model Suspended Sediment Transport: Application to Hyperpycnal and Hypopycnal Plumes
(Global-Science Press, 2017)
We propose a multi-layer approach to simulate hyperpycnal and hypopycnal plumes in flows with free surface. The model allows to compute the vertical profile of the horizontal and the vertical components of the velocity ...

A well-balanced finite volume-augmented lagrangian method for an integrated Herschel-Bulkley model
(Plenum Press, 2012)
We are interested in the derivation of an integrated Herschel-Bulkley model for shallow flows, as well as in the design of a numerical algorithm to solve the resulting equations. The goal is to simulate the evolution of ...

On well-balanced finite volume methods for non-conservative non-homogeneous hyperbolic systems
(Society for Industrial and Applied Mathematics, 2007)
In this work we introduce a general family of finite volume methods for non-homogeneous hyperbolic systems with non-conservative terms. We prove that all of them are “asymptotically well-balanced”: They preserve all smooth ...
