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.
Debris flows are fast-moving landslides that can cause severe damage and loss of life. Learn about the factors that trigger debris flows, how to recognize them, and how to prepare for them from the U.S. Geological Survey.
Learn what a debris flow is, how it forms, and why it is so dangerous. See videos, pictures, maps, and examples of debris flows from around the world.
Learn about debris flow, a mixture of water and particles driven by gravity, and its physical properties and hazards. Explore the latest research on debris flow rheology, experiments, and kinetic theory.
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.
Table of contents. READINGS. 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.
1 de dic. de 2019 · Debris flows represent one of the most dangerous types of mass movements, because of their high velocities, large impact forces and long runout distances. This review describes the available debris-flow monitoring techniques and proposes recommendations to inform the design of future monitoring and warning/alarm systems.
