Summary of Papers

Ancey-sediment	A statistical look at sediment transport

Bazant-kinematic	A model of particle motion in a bin/hopper

Bouchard-avalanches	A physicists avalanche model based on rolling, sliding and hopping grains

Eggers-vibration	A continuum model of the vertical vibration of a thin layer of granular material

Gray-segregation	Basic segregation model which now includes an interstitial fluid

Gremaud-jenike_compaction	An examination of a simple model of compaction of a powder as air escapes
