WebbAs we discussed previously, a landslide is only one of the many kinds of mass movements. Gravity is also responsible for several different forms of sediment relocation. Other major categories of mass movement include flows, creep and slump. Flows are the result of water mixing with sediment to form a soupy mass of rock, water, soil and other ...

WebbThere are generally three types of creep: Seasonal, where movement is within the depth of soil affected by seasonal changes in soil moisture and soil temperature. Continuous, where shear stress continuously exceeds the strength of the material. Progressive, where slopes are reaching the point of failure as other types of mass movements.
