In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure. Upscaled models are developed and it is shown that the presence of material heterogeneities may give rise to additional non-equilibrium terms in the governing equations or to hysteresis in the averaged constitutive relationships.GeoPlanet.Groundwater flowMathematical modelsPorous materialsPermeabilityMathematical modelsTransport theoryMathematical modelsGroundwater flowMathematical models.Porous materialsPermeabilityMathematical models.Transport theoryMathematical models.551.48Szymkiewicz Adam1063523MiAaPQMiAaPQMiAaPQBOOK9910437952003321Modelling Water Flow in Unsaturated Porous Media2532879UNINA
