Geological media exhibit heterogeneities in their hydraulic and chemical properties, which
can lead to enhanced spreading and mixing of the transported species and induce an …

This review provides an overview of concepts and approaches for the quantification of
passive, non-reactive solute mixing in steady uniform porous media flows across scales …

We study the intermittency of fluid velocities in porous media and its relation to anomalous
dispersion. Lagrangian velocities measured at equidistant points along streamlines are …

We investigate the spatiotemporal nonlocality underlying fractional-derivative models as a
possible explanation for regional-scale anomalous dispersion with heavy tails. Properties of …

Reactive transport (RT) couples bio-geo-chemical reactions and transport. RT is important to
understand numerous scientific questions and solve some engineering problems. RT is …

The geologic architecture in sedimentary reservoirs affects the behavior of density-driven
flow and the dispersion of CO2-rich brine. The spatial organization and connectivity of facies …

Flow and transport through fractured geologic media often leads to anomalous (non‐
Fickian) transport behavior, the origin of which remains a matter of debate: whether it arises …

We study the nature of non‐Fickian particle transport in 3‐D porous media by simulating
fluid flow in the intricate pore space of real rock. We solve the full Navier‐Stokes equations …

We report the emergence of anomalous (non-Fickian) transport through a rough-walled
fracture as a result of increasing normal stress on the fracture. We show that the origin of this …

Random walk (RW) methods are recurring Monte Carlo methods used to model convective
and diffusive transport in complex heterogeneous media. Many applications can be found …
