In a significantly revised English edition the text provides a solid course on mechanics of porous & fractured media (mainly of geomaterials). Part I focuses on the continuum theory of the dynamic fracture and deformation of bodies with complex rheology, including the dilatancy theory.

In this work, we develop a novel Lagrangian model able to predict solute mixing in heterogeneous porous media. The Spatial Markov model has previously been used to predict effective mean conservative transport in flows through heterogeneous porous media. In predicting effective measures of mixing on larger scales, knowledge of only the mean transport is by: 3.

Introduction. The classical model for solute transport in the subsurface is the advection–dispersion equation (ADE). It embodies advection, molecular diffusion and mechanical dispersion as mass transfer processes (1) ∂ C ∂ t =-∑ i ∂ ∂ x i q i A + q i d + q i D where C is the solute concentration, t is the time and x i is the spatial coordinate in direction i.

Transverse dispersive mixing plays an important role in controlling natural attenuation of contaminant plumes and the performance of engineered remediation strategies. The extent of transverse mixing can be significantly affected by porous media heterogeneity and anisotropy.
