An earthflow (earth flow) is a downslope viscous flow of fine-grained materials that have been saturated with water and moves under the pull of gravity. It is an intermediate type of mass wasting that is between downhill creep and mudflow. The types of materials that are susceptible to earthflows are clay, fine … See more Earthflows are just one type of mass movement that can occur on a hill slope. It has been recognized as its own type of movement since the early 20th century. Earthflows are one of the most fluid types of mass movements. … See more Earthflows vary in velocity of flow depending partly on the consistency of the flow for the speed of the entire movement, usually meaning how much water is in the material of the hill slope before the slope fails. Though water is often the key factor in slope failure, … See more The areas most at risk for earthflows are: • Slopes that have been undercut or loaded with more sediment for human construction See more Earthflows can have sudden impacts on the amount of sediment that is deposited into a river system, which can have effects on the life in and around the river itself. They can also cause damage to roads and constructions built near the slope. One of the best mitigation … See more • Landslide mitigation See more • Slumgullion earthflow, USGS Bulletin 2130, a National Natural Landmark in Colorado, USA. • New landslide video: a fascinating and huge Russian earthflow - American Geophysical Union, 17 April 2015 See more WebA tag already exists with the provided branch name.

WebClay-rich diamictons may form high, steep slopes where incised by streams and are subject to earthflows when saturated. Locally forms steep-sided, sinuous ridges (eskers) up to 12 m high and 4-5 m wide at the crest. Thickness ranges from a thin and patchy veneer over ice-scoured bedrock to more than 25 m thick. WebEarthflow is a mass wasting process. This is where a portion of a water-saturated slope moves a partial distance downhill typically after a heavy rainfall.
