TL;DR: In this paper, electrical resistivity tomography (ERT) was used to image the resistivity distribution before and during two infiltration experiments, and the change in resistivity associated with the plume of wetted soil was imaged as a function of time.

TL;DR: In this article, a reactive transport modeling of CO2 storage in a shele-capped sandstone aquifer at Sleipner has elucidated and established key parametric dependencies of these fundamental processes, the associated trapping mechanisms, and sequestration partitioning among them during consecutive ten-year prograde and retrograde (post-injection) regimes.

TL;DR: In this paper, a macroscopic motion equation for a fluid phase (Darcy's law) is derived, incorporating the effect of potentials and surface forces, and the relationship of advective fluxes to the gradients of macro-scopic chemical potentials.

TL;DR: A methodology combining Bayesian inference with Markov chain Monte Carlo (MCMC) sampling is applied to a real accidental radioactive release that occurred on a continental scale at the end of May 1998 near Algeciras, Spain.

TL;DR: In this article, the position of the fracture liquid front as a function of time, under some simplifying assumptions, is shown to obey a nonlinear integrodifferential equation, showing that the movement of the liquid front exhibits three major flow periods: (1) at early time, the frontal position is determined by the fracture inlet boundary condition and the gravity-driven flow behavior of the fractures with negligible influence by the matrix; (2) at intermediate time, matrix imbibition retards the frontal advance against the pull of gravity; (3) at late time,
