Bedrock erosion by granular flow, Appendix 1: Erosion sample photographs and erosion maps

Photographs and erosion maps for the experiments in Hsu, L. (2010), Bedrock erosion by granular flow, Ph.D thesis, University of California, Berkeley. Two pdf files. Bedrock erosion experiments were performed in a 4 meter diameter, 80 cm wide vertically-rotating drum flume. Shallow flows were composed of clay, silt, sand, gravel, cobbles, and water. The flows eroded synthetic bedrock (concrete) samples. Erosion maps were made by differencing the topography before and after the flow with MATLAB.
