Characterizing the Impacts of Multi‐Scale Heterogeneity on Solute Transport in Fracture Networks

Geophysical Research Letters, 2023
We model flow and transport in fracture networks with varying degrees of fracture‐to‐fracture aperture heterogeneity and network intensity to show how changes in these properties can cause the emergence of anomalous flow and transport behavior.
