We investigated the late‐time (asymptotic) behavior of tracer test breakthrough curves
(BTCs) with rate‐limited mass transfer (eg, in dual‐porosity or multiporosity systems) and …

The classical Fickian model for solute transport in porous media cannot correctly predict the
spreading (the dispersion) of contaminant plumes in a heterogeneous subsurface unless its …

Estimates of mass transfer timescales from 316 solute transport experiments reported in 35
publications are compared to the pore‐water velocities and residence times, as well as the …

We generalize the streamline approach to transient pressure applications by introducing a"
diffusive" time of flight along streamlines. This allows us to define drainage areas or volumes …

An asymptotic approach to the solution of the transport equation, in the limit of rapid spatial
and temporal variation, produces an extremely efficient formalism for the inversion of tracer …

This pore-scale modeling study in saturated porous media shows that compound-specific
effects are important not only at steady-state and for the lateral displacement of solutes with …

A field-scale natural gradient tracer experiment with bromide, uranin and lithium was
conducted in a heterogeneous aquifer at Krauthausen, Germany. The temporal and spatial …

Quantification of pollutant mass fluxes is essential for assessing the impact of contaminated
sites on their surrounding environment, particularly on adjacent surface water bodies. In this …

Miscible and immiscible viscous fingering in porous media are undesirable for many
engineering applications such as chemical enhanced oil recovery, contaminant transport …

We investigate a backward problem for a time-fractional diffusion process in
inhomogeneous media, which aims to determine the initial status of some physical field such …
