Fluid transport in fractured porous media plays an essential role in a wide range of subsurface systems. These systems are governed by strongly coupled thermal-hydraulic-mechanical-chemical (THMC) processes, where multiphysics interactions across fractures and matrix domains control flow behavior, reaction pathways, and long-term system evolution. Accurate prediction of these processes remains a significant challenge due to the complexity of fracture networks, nonlinear feedback mechanisms, and the wide range of spatial and temporal scales involved. This session aims to highlight recent developments in the modeling and characterization of coupled THMC processes in fractured subsurface systems through experimental, numerical, and theoretical approaches. We welcome submission of abstracts on:

1. Advanced numerical methods for multiphysics coupling and their applications
2. AI/ML-assisted modeling, surrogate development, and physics-informed learning
3. Integration of geophysical observations with modeling, including inversion and data assimilation
4. High-performance strategies or open-source tools that advance community modeling capabilities
