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.
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.
Debris flow - SpringerLink
网页A debris flow forms when a mass of sediment is mobilized and transformed into a flowing slurry. Most commonly, a debris flow results from a landslide triggered by torrential rainfall, rapid snowmelt, or an earthquake, and in subaqueous environments by additional combinations of rapid sedimentation, gas release, and storm-wave loading.
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.
Advances in Debris-flow Science and Practice | SpringerLink
网页This book provides a comprehensive overview of all facets to date, including initial hazard assessments, detailed quantitative risk assessments, debris-flow warning systems, debris-flow mitigation structure designs, and failures of mitigation works, as well as new topics such as climate change effects on debris flows.
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 - 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.
Lahars and debris flows: Characteristics and impacts
网页2020年2月1日 · Debris flows (DFs) are mixtures of debris and water with high sediment concentrations that move downslope due to gravity as surging sediment slurries (Coussot and Meunier, 1996; Vallance, 2000). DFs comprise a solid phase of at least 60 vol% (>80 wt%), thoroughly mixed with water.
The physics of debris flows - Iverson - 1997 - Reviews of …
网页1997年8月1日 · Analyses of flows of dry, granular solids and solid-fluid mixtures provide a foundation for a comprehensive debris flow theory, and experiments provide data that reveal the strengths and limitations of theoretical models.
