Particle-Scale Dynamics in Earth and Planetary-Surface Evolution and How They Scale Up to System Dynamics

Session ID#: 85556

Session Description:
In recent decades, experiments, field observations, and data from models have indicated the dynamics of particle-scale dynamics, such as “granular physics”, play an important role in the evolution of landscapes.  Examples include the erosion behavior and statistics of debris flows and snow avalanches; sorting behaviors in transported sediments; small apparently isolated movements in hillslope creep, and collisional dynamics in the evolution of dune fields. Still, there is a challenge in both (a) accounting quantitatively for these particle-scale dynamics and then (b) upscaling them to the landscape scale.   This session welcomes contributions from physical experiments, field work and modeling work that contributes to our understanding of the importance of particle-scale physics to earth and planetary surface processes and the upscaling of particle-scale dynamics into continuum-like frameworks capable of representing large-scale system behaviors, influence on geomorphology, and associated hazards.
