Flow results from cold and warm tests Flow results from cold and warm tests The results of Raack’s experiment, with the “cold” sediment in the top row showing very little flow. The bottom row is the “warm” experiment. The middle column highlights different kinds of flow (blue = overland flow, green = percolation, red = pellets, yellow = dry avalanches/saltation), and the right column highlights elevation changes in the sediment post-flow.
