TL;DR: In this paper, the authors conducted quasi-two-dimensional flow-through experiments at the laboratory bench scale to investigate in detail the mass transfer of O 2 in a fluctuating capillary fringe and evaluated the effects of different boundary conditions such as single drainage and imbibition events as well as periodic fast and slow water table fluctuations.

TL;DR: It is shown that vertical hydrodynamic dispersion in the water-saturated part of the capillary fringe is the process limiting the mass transfer of oxygen in the unsaturated/saturated interface.

TL;DR: In this paper, the influence of Coulombic effects on transport of charged species in saturated porous media in advection-dominated flow regimes was studied and a multicomponent formulation of transverse hydrodynamic dispersion was proposed to investigate transport of dilute electrolyte solutions.

TL;DR: In this article, a nonlinear parameterization of transverse dispersion has been proposed to predict reactive transport at the Darcy scale in porous media, assuming a constant dispersivity property of the porous medium.

TL;DR: In this paper, the effects of Coulombic interactions during transport of electrolytes in heterogeneous porous media under steady-state flow and transport conditions were investigated under advection-dominated conditions, where flow diverging around a low-permeability inclusion and flow focusing in high permeability zones occurred.
