Characterizing the impacts of multi-scale heterogeneity on solute transport in fracture networks

Matthew R. Sweeney, Jeffrey D. Hyman, Daniel O'Malley +4

We model flow and transport in three-dimensional fracture networks with varying degrees of fracture-to-fracture aperture/permeability heterogeneity and network density to show how…
