Both types are generally mixtures of various kinds of materials of different sizes, which are typically sorted by size upon deposition.Mudflows are often called mudslides, a term applied indiscriminately by the mass media to a variety of mass wasting events. This gives rise to such names as "mudflow," "earthflow," and "soil flow." The higher the initial ground water content, and the greater steepness of the originating slope, the more rapidly and farther the mass can flow, and together with the volume of the mass, the greater the force it can exert.

What is the primary difference between the earthflow and mudflow? Explain the process of soil creep. Erosion is the physical removal and transportation of weathered material by water, wind, ice, or gravity.Mass wasting is the transfer or movement of rock or soil down slope primarily by gravity. If it contains a high percentage of fine material and flows with a high degree of fluidity it is called a mudflow. Earthflows usually begin in a large basin on the upper part of a slope where debris and weathered material accumulate; the movement, usually set off by heavy rainfall, may be relatively slow or very fast, depending on the amount of water present, the angle of the slope, and other aspects of the terrain. What's the importance of studying abroad? Earthflow - Sheet or stream of soil and rock materials saturated with water and flowing downslope by force of gravity and it shows that it is an intermediate stage between creep and mudflow. It has a higher density and viscosity than a streamflow and can deposit only the coarsest part of its load; this causes irreversible sediment entrainment. What is the negative effects of mudflows? very rapid to extremely rapid surging flow. The main difference between mudslide and earthflow is that mudslide is the movement of soil that has been mixed with water while earthflow is the movement of soil portion that has been made moist by water. A debris flow is the movement of a water-laden mass of loose mud, sand, soil, rock and debris down a slope. Flow velocities vary from slow, when behaviour is plastic, to rapid, when behaviour is more liquid, and reflect variations in water content. Earthflow. dominated by coarse grained material.
