Flow and solute transport in individual fractures in rocks
Flow and solute transport in individual fractures in rocks
Contaminants migrate by flow and diffusion in fractures in rocks. We perform experiments of flow and diffusion in variable aperture fractures and develop models to predict the migration of solutes in general and of radionuclide decay chains. Diffusion in the rock matrix and sorption on micropore surfaces are accounted for. Diffusion in stagnant or slowly moving water in the fracture is accounted for. We also study the impact of rock stresses as they change the fracture aperture by compression and shear.
