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 ...

Some Geophysical Applications with Finite Volume Solvers of Two-Layer and Two-Phase Systems
(Springer, 2017)
There exists in the literature a huge range of geophysical applications that have been modeled trough two-layer or two-phase models. In this work first some averaged two-layer and two-phase models are presented. We focus ...

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 ...

Well-balanced Finite Volume schemes: some stability and convergence results
(Universidad de Zaragoza, 2003)
We report a stability and convergence analysis for some simplified well-balanced Finite Volume solvers of Hyperbolic Systems of Conservation Laws. These are specific solvers, recently introduced, that balance all steady ...

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 ...
