WebHowever, earthflows never leave such scars. Debris flows generally occur within semiarid areas and tend to be restricted to channels, whereas earthflows most often occur on hillsides in humid areas. Debris flows are composed entirely of very large rocks and boulders, whereas earthflows are composed of very small sediments. WebA mudflow is different from an earthflow in that mudflow moves along the surface of a slope and down established drainage channels whereas earthflow involves a slope failure and has little or no relationship to the drainage network, mudflows are more rapid and also more dangerous than earthflows. 3. how can we stop single use plastic
