We are interested in the physics of flow, reaction, and deformation in soil and rock. To study that, the PMV lab is replacing the soil and rock with an equivalent transparent porous material developed in the lab. The transparent porous material allows direct quantification of the following processes occurring in soil and rock: transport in porous media, reaction rates of chemicals during transport, displacement of resident phase in the porous media by a miscible or immiscible phase, and deformation of the porous material during the transport.
