The complexity of hydrogeology rests on the nature of subsurface geologic formations, which present heterogeneities at all scales, and are the locus of coupled, non-trivial physical, chemical, and biological processes. Additionally, they are intricately influenced by other portions of the Earth system, as well as anthropogenic activity. In the Porous Media Flow Lab, we aim to advance our knowledge of fluid flow, transport, and reactions in geological formations and improve simulation and prediction by: visualizing and quantifying complex coupled physical and geochemical processes, such as multi-phase flow dynamics and reactive transport, at the pore (µm) to core (cm) scale. characterizing and monitoring subsurface systems at the field scale.
