1. The rapid, downward mass movement of particles coarser than sand, often including boulders one meter or more in diameter, at a rate ranging from 2 to 40 kilometers per hour. Debris flows occur along fairly steep slopes. 2. The material that descends in such a flow. deflation The process by which wind erodes bedrock by picking up and transporting loose rock particles.
The rapid downslope movement of debris (rock, soil, and mud).
A type of landslide that is a mixture of soil, water, logs, and boulders that travel quickly down a steep channel.
a combination of water-saturated loose soil, rock, organic matter, and air, with material varying in size from grains of clay to large boulders
a form of rapid mass movement in which a combination of loose soil, rock, organic matter, air, and water mobilize as a slurry that flows downslope (fig
a mixture of mud and rock debris that looks and behaves like flowing concrete
a moving mass of rock fragments, mud, soil, and enough water to keep the mass fluid
a rapid flow of water saturated sediment occurring in areas of higher relief
a water-fluidized flow of rock and soil that moves down slope
A moving mass of rock fragments, soil, and mud, more than half of the particles being larger than sand size. () Debris flows usually occur on fairly steep slopes. Term also refers to the material that occurs in such a flow and that can be recognized in sedimentary deposits.
a flowing mixture of water and rock debris, sometimes referred to as a lahar (originating at a volcano) or mudflow
Dense, incoherent mixture of water, rock, and soil that flows downslope at speed of 2 to 40 kilometers/hour (1 to 25 miles/hour).
slurry of rock, water, mud, and organic debris moving down mountain slopes and stream courses.
A mixture of water-saturated rock debris that flows downslope under the force of gravity (also called lahar or mudflow).
A type of landslide made up of a mixture of water-saturated loose soil, rock, organic matter, and air, with a consistency similar to wet cement. Debris flows move rapidly downslope under the influence of gravity. Sometimes referred to as earthflows or mudflows.
A type of landslide made up of a mixture of water-saturated rock debris and soil with a consistency similar to wet cement. Debris flows move rapidly downslope under the influence of gravity. Sometimes referred to as earth flows or mud flows.
Mass transport process involving a slurry of sediment (of a variety of different grain sizes from clays to boulders) and water; debris flows can be a common process by which sediments are transported onto alluvial fans in desert regions
A rapid moving mass of rock fragments, soil, and mud, with more that half of the particles being larger that sand size.
Mass of rock and(or) sediment that becomes unstable and moves downslope under its own weight.
A downslope movement of mud mixed with larger rock fragments.
A debris flow (also called a mudflow or lahar) is a moving mixture of rock, water, and other debris.
A fluid mass movement of rock fragments supported by a muddy matrix. Debris flows differ from earthflows in that they generally contain coarser material and move faster than earthflows.
Debris flows are often referred to as mudslides, mudflows, jökulhlaups, or debris avalanches. There is also a debris flow type that has rocky front called 'the head' and a 'tail, like wet concrete. This debris flow has been well reported in the scientific literature.
