The immense diversity of microbial life found in the vadose zone reflects the extremely
heterogeneous and highly dynamic aquatic and chemical environments formed within soil …

Scientific imaging represents an important and accepted research tool for the analysis and
understanding of complex natural systems. Apart from traditional microscopic techniques …

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 propose a new experimental set up to characterize mixing and reactive transport in
porous media with a high spatial resolution at the pore scale. The analogous porous …

Multiple numerical approaches have been developed to simulate porous media fluid flow
and solute transport at the pore scale. These include 1) methods that explicitly model the …

Water that flows around a biofilm influences the transport of solutes into and out of the
biofilm and applies forces to the biofilm that can cause it to deform and detach. Engineering …

Contaminant hydrogeological processes occurring in porous media are typically not
amenable to direct observation. As a result, indirect measurements (eg, contaminant …

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 …

We study scalar mixing in heterogeneous conductivity fields, whose structural disorder
varies from weak to strong. A range of stretching regimes is observed, depending on the …

This study investigates the functional correspondence between porescale hydrodynamics,
mass transfer, pore structure and biofilm morphology during progressive biofilm colonization …
