Debris flow erosion experiments

Description: 

Experiments to study bedrock erosion by debris-flows. We measured erosion of synthetic bedrock and bed-normal force in a suite of granular flows in a 4 meter diameter, 80 cm wide vertically rotating drum. The flows were composed of granular material for both narrow (gravel-water) and wide (muddy, sand-gravel-cobble) grain-size distributions, with grain size ranging from clay-size to cobble-size.
