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 ...

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 ...

Well-balanced finite volume schemes for 2D non-homogeneous hyperbolic systems. Application to the dam-break of Aznalcóllar.
(Elsevier, 2008)
In this paper, we introduce a class of well-balanced finite volume schemes for 2D non-homogeneous hyperbolic systems. We extend the derivation of standard finite volume solvers for homogeneous systems to non-homogeneous ...

A new Savage-Hutter type model for submarine avalanches and generated tsunami
(Elsevier, 2008)
In this paper we present a new two-layer model of Savage-Hutter type to study submarine avalanches. A layer composed of fluidized granular material is assumed to flow within an upper layer composed of an inviscid fluid (e. ...

Extension of WAF type methods to non-homogeneous Shallow Water Equations with pollutant
(Plenum Press, 2008)
This paper deals with the extension of the WAF method to discretize Shallow Water Equations with pollutants. We consider two different versions of the WAF method, by approximating the intermediate waves using the flux of ...

On new erosion models of Savage-Hutter type for avalanches
(Springer, 2008)
In this work, we study the modeling of one-dimensional avalanche flows made of a moving layer over a static base, where the interface between the two can be time dependent. We propose a general model, obtained by looking ...
