Particle Size Segregation in Granular Avalanches

When particles with different material properties are segregated by size or density they often have a subtle feedback on the local mobility of the granular material, which can significantly modify the bulk flow. Perhaps the most striking example of this segregation-mobility feedback occurs in geophysical mass flows, such as debris-flows, dense pyroclastic avalanches and snow avalanches. Larger ...
