Scope 
Flow and transport through porous and fractured media are fundamental to many challenges in earth science and geological engineering. Yet, capturing the governing physics across scales, from pores to reservoirs, remains a formidable task due to complex heterogeneity, nonlinear processes, and scale-dependent behavior. This session invites contributions that advance our predictive understanding of porous and fractured systems through innovative use of imaging, theory, simulation, and artificial intelligence. We particularly welcome studies that bridge scales, address heterogeneity, quantify uncertainty, and demonstrate applications to real-world systems, such as hydrothermal/enhanced geothermal energy, groundwater, soils, energy materials, hydrocarbon production and subsurface storage.
Topics of interest include (but are not limited to):
- Pore-scale imaging and simulation of flow, transport, and other physical processes (Digital Rock Physics)
- Upscaling/homogenization/multiscale theoretical frameworks
- AI-based surrogate modeling and discovery
- Coupled processes (thermal, mechanical, hydraulic, chemical, biological) across scales
- Validation, uncertainty quantification, and comparison with experiments or field data
- Application domains: geothermal/volcanism, groundwater, environmental remediation, carbon sequestration, energy materials, etc.
