WebJun 11, 2024 · The earthflow material contained a large amount of expansive clay. Clay swells when it has more water and shrinks when there is less water. The scientists hypothesized, from the correlation of the swell pressures measured in the laboratory and field with the earthflow movement, that the presence and amount of clay in the … WebFirstly, marine processes erode and undermine the base of the cliff. Rainwater infiltrates the cliff through unconsolidated, porous material (e.g. boulder clay). This then creates a slip plane. The weight of the saturated clay causes the material to slump along the slip plane. The process is illustrated in the diagram below.

WebVelocities 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, hilly fronts. A common trigger for an earthflow is the undercutting of the slope by erosion from wave action or rivers or by construction projects. 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 sand and silt, and fine-grained pyroclastic material.
