Debris Flow

A moving mass of rock fragments, soil, and mud, more than half of the particles being larger than sand size. Slow debris flows may move less than 1 m per year; rapid ones reach 160 km per hour. Debris flows are very fluid and contain a high content of water.Neuendorf, K.K.E., Mehl, J.P., Jr., and Jackson, J.A., ed., 2005, Glossary of Geology: American Geological Institute, 799 p.
