      A consistent intermediate wave speed for a well-balanced HLLC solver.  [Article]

      Fernández Nieto, Enrique Domingo; Bresch, Didier; Monnier, J. (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 ...

      A corrector for the Sverdrup solution for a domain with islands  [Article]

      Bresch, Didier; Guillén González, Francisco Manuel; Rodríguez Bellido, María Ángeles (Taylor & Francis, 2004-03)
      In this paper we look at the influence of the Coriolis force on the quasi-geostrophic equations on a domain with islands. We prove that asymptotically we obtain the solution of the Sverdrup equation with homogeneous Dirichlet ...

      A new Savage-Hutter type model for submarine avalanches and generated tsunami  [Article]

      Fernández Nieto, Enrique Domingo; Bouchut, F.; Bresch, Didier; Castro Díaz, Manuel Jesús; Mangeney, A. (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. ...

      A note on a degenerate elliptic equation with applications for lakes and seas  [Article]

      Bresch, Didier; Lemoine, Jérôme; Guillén González, Francisco Manuel (Texas State University, 2004)
      In this paper, we give an intermediate regularity result on a degenerate elliptic equation with a weight blowing up on the boundary. This kind of equations is encountoured when modelling some phenomena linked to seas or ...

      Asymptotic derivation of a Navier condition for the primitive equations  [Article]

      Bresch, Didier; Guillén González, Francisco Manuel; Masmoudi, Nader; Rodríguez Bellido, María Ángeles (IOS Press, 2003-03)
      This paper is devoted to the establishment of a friction boundary condition associated with hydrostatic Navier-Stokes equations (also called primitive equations). Usually the Navier boundary condition is used, as a wall ...

      Deducción y simulación numérica de un nuevo modelo de avalanchas submarinas  [Presentation]

      Fernández Nieto, Enrique Domingo; Bouchut, François; Bresch, Didier; Castro Díaz, Manuel Jesús; Mangeney, Anne (2007-09)
      En este trabajo se estudia un nuevo modelo de tipo Savage-Hutter para avalanchas submarinas. El modelo obtenido es de tipo aguas someras bicapa en el que la capa superior representa al fluido y la capa inferior representa ...

      Derivation of a bilayer model for shallow water equations with viscosity. Numerical validation  [Article]

      Narbona Reina, Gladys; Zabsonré, J.D.; Fernández Nieto, Enrique Domingo; Bresch, Didier (Tech Science Press, 2009)
      In this work we present a new two-dimensional bilayer Shallow-Water model including viscosity and friction effects on the bottom and interface level. It is obtained following [[6]] from an asymptotic analysis of non-dimensional ...

      Local strong solution for the incompressible Korteweg model  [Article]

      Bresch, Didier; Guillén González, Francisco Manuel; Lemoine, Jérôme; Rodríguez Bellido, María Ángeles; Sy, Mamadou (Elsevier, 2006-02)
      We consider a Navier-Stokes type system with a Korteweg stress tensor, coupled with a concentration equation without diffusion. We give a result concerning the local in time existence (and uniqueness) of strong solution ...

      On the uniqueness of weak solutions of the two-dimensional primitive equations  [Article]

      Bresch, Didier; Guillén González, Francisco Manuel; Masmoudi, Nader; Rodríguez Bellido, María Ángeles (Ohio University Press, 2003-01)
      The uniqueness of weak solutions of the primitive equations with Dirichlet boundary conditions at the bottom is an open problem even in the two dimensional case. The aim of this paper is to prove the uniqueness of weak ...

      Regularidad anisótropa de un problema de Ecuaciones Primitivas  [Presentation]

      Bresch, Didier; Guillén González, Francisco Manuel; Rodríguez Bellido, María Ángeles (2007-09)
      En este trabajo estudiamos la regularidad de las Ecuaciones Primitivas (EP) del Océano, con condición de contorno sobre ∂zv en el fondo, siendo v la velocidad horizontal y z la variable de espacio vertical. Dicha condición ...

      Two shallow-water type models for viscoelastic flows from kinetic theory for polymers solutions  [Article]

      Narbona Reina, Gladys; Bresch, Didier (Dunod, 2013)
      In this work, depending on the relation between the Deborah, the Reynolds and the aspect ratio numbers, we formally derived shallow-water type systems starting from a micro-macro description for non-Newtonian fluids in a ...

      Uniqueness of solution for the 2D Primitive Equations with friction condition on the bottom  [Presentation]

      Bresch, Didier; Guillén González, Francisco Manuel; Masmoudi, Nader; Rodríguez Bellido, María Ángeles (2001)
      Uniqueness of solution for the Primitive Equations with Dirichlet conditions on the bottom is an open problem even in 2D domains. In this work we prove a result of additional regularity for a weak solution v for the Primitive ...
