  journal={SIAM J. Appl. Math.},
A theory for the solution of the Riemann problem for a one-dimensional, quasi-linear, 2$\times$2 system of conservation laws describing reactive transport in a permeable medium with pH-dependent adsorption is developed. The system is strictly hyperbolic and nongenuinely nonlinear because the adsorption isotherms are not convex functions. The solution comprises nine fundamental structures, which are a concatenation of elementary and composed waves. In the limit of low pH, the isotherms reduce to…

pH-dependent transport of metal cations in porous media.

The results suggest that the interplay between pH-dependent adsorption and hydrodynamic dispersion can give rise to the rapid migration of metals through reactive porous media with potential effects on, for example, the performance of subsurface engineering infrastructures for pollutant containment, the mobilization of metal contaminants by brine acidified upon contact with CO2 during geologic carbon storage, and the chromatographic separation processes in industrial applications.

Chromatographic analysis of the acidity-salinity transport system.

Challenges in Coupling Acidity and Salinity Transport in Porous Media.

A suite of column flood experiments through silica sand is conducted, systematically varying salinity and acidity conditions, to highlight the difficulty in applying reactive transport models to realistic media under both basic and acidic conditions with a single set of parameters.



Waves in a Two-Component System: The Oxide Surface as a Variable Charge Adsorbent

Concentration waves, the solutions of the Riemann problem, are calculated in the framework of multicomponent chromatography. Unlike ion exchange surfaces, oxides bind cations by predominantly

Analytical Solution to the Riemann Problem of Three-Phase Flow in Porous Media

In this paper we study one-dimensional three-phase flow through porous media of immiscible, incompressible fluids. The model uses the common multiphase flow extension of Darcy’s equation, and does

Local Equilibrium Theory for the Binary Chromatography of Species Subject to a Generalized Langmuir Isotherm

The local equilibrium theory of chromatography is applied to binary systems subject to the generalized Langmuir isotherm. This newly introduced adsorption isotherm allows describing a variety of

Transport of ion‐exchanging solutes in groundwater: Chromatographic theory and field simulation

Equations describing the transport of ion-exchanging solutes governed by local chemical equilibrium through a saturated porous medium are well established in the literature. Concentration profiles

The Riemann problem for a nonstrictly hyperbolic system modeling nonisothermal, two-phase flow in a porous medium

The Riemann problem for a $2 \times 2$ system of conservation laws arising in reservoir mechanics is solved. Entropy conditions for the system are discussed, including an explicit expression for an

Multicomponent exchange and subsurface solute transport: Characteristics, coherence, and the Riemann Problem

The Riemann problem is solved for the ternary exchange system using the method of characteristics and the pattern of composition changes is found to follow the right eigenvector paths in composition space, and the eigenvalues provide composition-dependent retardation functions.

Dispersion-Induced Chromatographic Waves

Motivated by field and laboratory observations of unusual wave propagation, we investigate the behavior of simple model problems involving transport with competitive adsorption of H+ and a metal

Anomalous Reactive Transport in the Framework of the Theory of Chromatography

The anomalous reactive transport considered here is the migration of contaminants through strongly sorbing permeable media without significant retardation. It has been observed in the case of heavy


The interfacial activity and mobility control of a chemical flooding process are affected by the concentration of the cationic and anionic species that travel with the surfactant and polymer. In this
