Most macrodispersion theories tacitly assume that a macrodispersivity tensor which works well when there is only small

In this paper, we offer a critical evaluation of these techniques as they relate specifically to the derivation of a field-scale advectio

Because of hydrodynamic dispersion, tracer particles which sample different regions of the reservoir tend to arrive at different times, and the resulting distribution encodes information about the flow and the large-scale geometry of the reservoir in a simple way. In particular, the transit-tim

A governing equation that describes particles that undergo Lévy motion, rather than Brownian motion, readily describes the highly skewed and heavy-tailed plume development at the MADE site.

On Perturbative Expansions to the Stochastic Flow Problem,n V . are necessary. In particular, when the two point correlation function for the conductivity is assumed to be exponential or Gaussian, it is possible to estimate the magnitude of . in terms of . and various length scales. The ratio of the integral scale in the main direction of flow (A,) to the
