Sediment gravity flows are represented by four different mechanisms of keeping grains within the flow in suspension. • Grain flow – Grains in the flow are kept in suspension by grain-to-grain interactions, with the fluid acting only as a lubricant. As such, the grain-to-grain collisions generate a dispersive pressure that helps prevent grains from settling out of suspension. Although common in terrestrial environ… WebJun 27, 2012 · Granular flow experiments on the interaction with stationary runout path materials and comparison to rock avalanche events.
