Data-driven and theoretical approaches for modeling, prediction, analysis of thermo-hydro-mechanical behaviors of frozen soil and rocks

Session ID#: 27208

Session Description:
Frozen soil and rocks are integrated parts of the Earth’s climate system. The timing, duration, thickness and distribution of frozen geomaterialsare dominated by heat exchanges between the environment and the land surface and the multiphysical coupling effects. During freezing and thawing cycles, microscopic mechanisms such as cryo-suction, thermal and hydraulic convection-diffusion, micro-cracks, enhanced particle interlocking and ice strengthening may have a profound effect on the land surfaces at the field scale. Yet, incorporating these complex micro-mechanical coupling effects for applications to earth system modeling remains difficult. This AGU session seeks contributions that innovate new techniques in (1) experimental and field works across length scales (e.g. micro-CT imaging, Lidar scan); (2) numerical modeling of frozen geomaterials, and (3) emerging technologies in data generation, collection and interpretation, such as climate-controlled experimental tests, data-driven machine learning and other approaches that improve the forward prediction and understanding of frozen geomaterials.
