MS2
Advances in Computation of Avalanches, Debris Flows, and Floods - Part I of III

10:30 AM - 12:30 PM
Room: Garden Salon 1

For Part II, see MS15

Pour water, sand, or poppy seeds out of a pitcher, and the dynamic appearance of each flow is strikingly similar. The reason for this similarity is that the physics governing the forces in inertially-dominated shallow flows that are driven by their own weight is similar for vastly different types of materials and flow conditions, providing unifying principles for all such flows (ranging from granular avalanches to water flooding). In this minisymposium, participants will present some of the latest results on advances in this emerging field, on topics including modeling and physics, advanced numerical techniques as well as empirical case studies.
