What is a debris flow? | U.S. Geological Survey - USGS.gov
网页Debris flows are fast-moving landslides that are particularly dangerous to life and property because they move quickly, destroy objects in their paths, and often strike without warning. They occur in a wide variety of environments throughout the world, including all 50 states and U.S. Territories.
What is a Debris Flow? Definition, Videos, Pictures, Maps
网页A debris flow is a moving mass of loose mud, sand, soil, rock, water and air that travels down a slope under the influence of gravity. To be considered a debris flow, the moving material must be loose and capable of "flow," and at least 50% of the material must be sand-size particles or larger.
Debris flow - Wikipedia
网页Debris flows are geological phenomena in which water-laden masses of soil and fragmented rock flow down mountainsides, funnel into stream channels, entrain objects in their paths, and form thick, muddy deposits on valley floors.
Debris Flow - an overview | ScienceDirect Topics
网页A debris flow is a mixture of water and particles driven down a slope by gravity. They typically consist of unsteady, non-uniform surges of mixtures of muddy water and high concentrations of rock fragments of different shapes and sizes.
Debris Flow: Causes, Effects, and Mitigation Strategies
网页Debris flow, also known as mudflow, is a geologic phenomenon that can have devastating consequences for communities and landscapes. In this comprehensive guide, we will explore the causes, effects, and mitigation strategies related to debris flow.
10.6: Debris Flows - Geosciences LibreTexts
网页2022年8月18日 · 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.
Debris flow - SpringerLink
网页A debris flow can form during a volcanic eruption when hot volcanic debris melts and mixes with snow and ice, or when crater lakes or near-surface groundwater are explosively expelled. A debris flow may also form when pore water is expelled during consolidation of a landslide deposit.
Debris Flow - SpringerLink
网页2016年1月1日 · Debris flow is an extremely rapid, flow-like mass movement, traveling in a steep, established channel and involving a saturated, unsorted mixture of granular soils, organics, and other debris (Hungr et al., 2001).
Debris-flow monitoring and warning: Review and examples
网页2019年12月1日 · 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.
