TL;DR: In this article, a Lagrangian framework is used for analysing reactive solute transport by a steady random velocity field, which is associated with flow through a heterogeneous porous formation, and the reaction considered is kinetically controlled sorption-desorption.

TL;DR: In this paper, a general framework to compute the statistical moments of q and of the associated total solute discharge Q and mass M is established, and the expected expected solute flux value is proportional to the joint probability density function (pdf) g1 of η, ζ and τ, whereas the variance of q is shown to depend on the joint pdf g2 of the same variables for two particles.

TL;DR: In this article, the effects of wall surface roughness on fluid flow through rock fractures were investigated using a wavelet analysis technique to define a mathematical criteri cercle for the problem.

TL;DR: In this paper, the authors investigated the longitudinal advective solute movement in heterogeneous porous media by considering the solute arrival time at a plane perpendicular to the mean fluid velocity, defined in terms of the stochastic properties of a statistically anisotropic hydraulic conductivity field.

TL;DR: In this paper, the covariance of the mass flux and cumulative mass flux is derived as functions of the injection volume and sampling area size relative to the scale of heterogeneity, and the result is illustrated for solute advection in three types of heterogeneous porous media: stratified formations, two-dimensional porous media; small perturbation approximation is used for the two-and three-dimensional cases.
