   Debris flows are accelerated downhill by gravity and tend to follow steep mountain channels that debouche onto alluvial fans or floodplains. The front, or 'head' of a debris-flow surge often contains an abundance of coarse material such as boulders and logs that impart a great deal of friction.

   Aug 18, 2022 · 10.6: Debris Flows. Debris flows are concentrated mixtures of water and loose rock and mineral material that flow downslope, usually in a preexisting channel, under the pull of gravity. Speeds range from a slow walk to a speeding automobile. They differ from ordinary sediment-transporting streamflow in that the motivating force for the ...

   May 6, 2019 · Debris flows are high-density slurries of water, rock fragments, soil, and mud that can have enormous destructive power. Wildfire can drastically increase the probability of debris flows in landscapes that have otherwise been stable. In 2010, the USGS developed the Cannon model to estimate postwildfire debris-flow probabilities and volumes in ...

   What is a debris flow?

   • The photograph was taken within several months of the debris flows occurring. Debris flows are geological phenomena in which water-laden masses of soil and fragmented rock rush down mountainsides, funnel into stream channels, entrain objects in their paths, and form thick, muddy deposits on valley floors.

   What are the conditions required for debris flow initiation?

   • In all cases the chief conditions required for debris flow initiation include the presence of slopes steeper than about 25 degrees, the availability of abundant loose sediment, soil, or weathered rock, and sufficient water to bring this loose material to a state of almost complete saturation (with all the pore space filled).

   What is the source area of a debris flow?

   • The source area of a debris flow must have: 1) a very steep slope, 2) an abundant supply of loose debris, 3) a source of abundant moisture, and 4) sparse vegetation. Identifying areas where debris flows have happened in the past or where these conditions are present is the first step towards developing a debris flow mitigation plan.

   What is a classic debris flow?

   • The classic debris flow has sediment concentrations by volume of over fifty percent—almost to the point at which the sediment particles lock together and prevent movement. It also is characterized by extremely poor sorting of the solid material, from clay-size particles to house-size boulders.

   A debris flow is a rapid mass movement of a concentrated mixture of sediment, organic matter, and water that can flow like a liquid yet can stop on sloping surfaces and form a nearly rigid deposit. Learn about the origins, behavior, and modeling of debris flows in subaerial and subaqueous environments from this encyclopedia entry.
