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

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 …

This text combines the science and engineering of hydrogeology in an accessible,
innovative style. As well as providing physical descriptions and characterisations of …

The hyporheic zone is often defined as where mixing of surface water and groundwater
occurs in shallow sediments beneath and adjacent to rivers. This mixing is credited with …

Transport of multicomponent electrolyte solutions in saturated porous media is affected by
the electrostatic interactions between charged species. Such Coulombic interactions couple …

The key role of small-scale processes like molecular diffusion and electrochemical migration
has been increasingly recognized in multicomponent reactive transport in saturated porous …

Low‐permeability aquitards, such as clay layers and inclusions, are of utmost importance for
contaminant transport in groundwater systems. Although most dissolved species …

In this study, we performed multitracer laboratory bench-scale experiments and pore-scale
simulations in different homogeneous saturated porous media (ie, different grain sizes) with …

Mixing processes significantly affect and limit contaminant transport and transformation rates
in the subsurface. The correct quantification of mixing in groundwater systems must account …

The solute transport regime is highly dependent upon the heterogeneity of the flow field. In
this study, the influence of eddies on conservative solute transport through a two …
