Fluid-solid reactions pose a challenge for modelling flow and transport in porous media due to the dynamic changes in the pore space and the associated alteration of the permeability. This project aims to use Magnetic Resonance Imaging and X-ray computer microtomography measurements on synthetic porous media made from glass beads and soil columns to experimentally elucidate differences in porosity-permeability relationships for three different fluid-solid reactions: salt precipitation during evaporation, microbially-induced calcite precipitation, and dissolution during chemical stimulation.
