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 …

Toxic organic contaminants may enter the subsurface as slightly soluble and volatile
nonaqueous phase liquids (NAPLs) or as dissolved solutes resulting in contaminant plumes …

Coupled modeling of subsurface multiphase fluid and heat flow, solute transport, and
chemical reactions can be applied to many geologic systems and environmental problems …

Reactive fluid flow and geochemical transport in unsaturated fractured rocks have received
increasing attention for studies of contaminant transport, ground-water quality, waste …

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 …

Background It is well established that the functioning of terrestrial ecosystems depends on
biophysical and biogeochemical feedbacks occurring at the soil-plant-atmosphere (SPA) …

Microbial activity in aquifers is controlled by the mixing between the reacting substrates.
Conventional modelling methods that are commonly used to analyze reactive transport of …

Subsurface contamination by organic chemicals is a pervasive environmental problem,
susceptible to remediation by natural or enhanced attenuation approaches or more highly …

Breakthrough curves of a conservative tracer in a heterogeneous two‐dimensional aquifer
are analyzed by means of their temporal moments. The average velocity and the …

The interplay between mixing and reactive processes plays a pivotal role in a range of
biogeochemical processes controlling the transport, transformation and turnover of chemical …
