Advances in Understanding and Modelling the Mechanics of Large-Scale Particulate Flows

Session ID#: 78716

Session Description:
Large-scale flows of particles, such as dust storms, snow avalanches, debris flows, rivers and turbidity currents, are some of the most dramatic natural phenomena on the Earth’s surface.  These flows operate across a range of environments, but are underpinned by the transport of material and its interactions with fluid motions. Despite their importance in sculpting the morphology of our environment, our understanding of the underlying dynamics of these flows quantitatively is in its relative infancy.  Even in simple contexts, motion cannot always be predicted, because the interactions between particles and interstitial fluid remain incompletely understood and poorly represented in models. Research advances come from the interplay between empirical observations, in laboratory or field, and developments of new quantitative models and simulations.  In this interdisciplinary and cross-cutting session, we welcome contributions that report and integrate empirical observations and mathematical modelling to advance of the understanding the mechanics of large-scale particulate flows.
