WebThe earthflow usually leaves a steep scarp behind where it separated from the hillside. Earthflows can be fast (a few hours) or slow (a few months). Velocities range from 1 millimeter per day to meters per day. Intermittent activity can continue for years as the earthflow continues to settle and stabilize. Earthflows typically have rounded ...
WebA slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. [1] … WebEarthflow A slow flow of earth lubricated by water, occurring as either a low-angle terrace flow or a somewhat steeper but slow hillside flow. Earthflow erosion was treated by afforestation, space-planted trees, localised close tree planting, gully control at the toe of the earthflow , graded diversion banks, surface smoothing and drainage.
