Hydrodynamics and geochemistry at multiple scales : characterizing preferential flow-paths and wormholes in evaporitic sediments

Abstract: The characterization of evaporitic aquifers for a better understanding of hydrodynamics and geochemical processes is of great importance, especially in environments where both the sustainability of unique ecosystems and the economic interests depend on aquifer features. This is the case of the Salar de Atacama (SdA) evaporitic nucleus, the "driving force" of this thesis, which prompt us to pursue two main objectives. First, characterizing the hydraulic behavior of the SdA nucleus, with special attention for th… Show more

“…Moreover, borehole inspection camera images from the SdA typically reveal small cavities after perforation. From a theoretical perspective, when you force a flux through an evaporitic salt, characterized by rapid dissolution kinetics, wormhole development must occur (Cabeza et al, 2020;Golfier et al, 2004;Trabucchi et al, 2021).…”
