Understanding the interaction of fluid flow with mechanical-chemical-biological-thermal-processes in fractured geological formations is critical for civil and industrial subsurface applications ranging from water and geothermal resource management, remediation of fractured aquifers, geologic carbon sequestration, and long-term radioactive waste isolation. In this session, we encourage submissions of recent research concerning mechanistic understanding and predictive capability for physical processes in fractured media. In particular, we seek research concerning: (1) experimental and field observations at the single fracture and network scales; (2) new theoretical and numerical modeling techniques focusing on direct numerical simulations in single fractures, discrete fracture network/matrix modeling, upscaling methodologies, and multi-scale methods; and (3) the integration of experimental data and modeling efforts for observational interpretation, prediction, and model validation. Various applications related to coupled flow and geomechanics, solute transport including colloids and bacteria, mixing and reaction, fluid/mineral interactions, and biofilm formation are all welcome.
