TL;DR: In this paper, a one-dimensional prototype geochemical transport model was developed in order to handle simultaneous precipitation-dissolution and oxidation-reduction reactions governed by chemical equilibria.

TL;DR: In this paper, the potential of 2D electrical imaging for the characterization of seawater intrusion using field data from a site in Almeria, SE Spain was investigated, and the authors quantified this capability in terms of the cumulative sensitivity associated with the measurement setup and showed that the mismatch between the targeted and imaged parameter values occurs from a certain sensitivity threshold.

TL;DR: Numerical simulations suggest that local dispersivity values may be as much as 40 times higher in the more severe clogged areas inside the column, and the bulk hydraulic conductivity and dispersivity parameters were almost recovered after disinfection of the columns.

TL;DR: In this paper, four different conceptual models based on alternative geological interpretations were formulated for a shallow 600 km2 aquifer system in Denmark comprising Quaternary deposits, and each of the four models was calibrated against groundwater heads and discharge measurements through inverse modeling.

TL;DR: In this article, a seawater intrusion experiment was carried out in a shallow coastal unconfined aquifer at Skansehage, Denmark, where stable isotopes, strontium isotopes and the elements Sr and Cl were measured to delineate the mixing of seawater and groundwater in the shallow aquifer and to determine the contribution from different water sources along the flow paths.
