What is a debris flow? | U.S. Geological Survey - USGS.gov
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 …
What is a Debris Flow? Definition, Videos, Pictures, Maps
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 - an overview | ScienceDirect Topics
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.
Emergency Assessment of Post-Fire Debris-Flow Hazards - USGS
Wildfire can significantly alter the hydrologic response of a watershed to the extent that even modest rainstorms can produce dangerous flash floods and debris flows. The USGS conducts post-fire debris-flow hazard assessments for select fires in the Western U.S.
Debris Flow: Causes, Effects, and Mitigation Strategies
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.
Post-Fire Debris Flows | U.S. Geological Survey - USGS.gov
2024年11月6日 — Fast-moving, highly destructive debris flows triggered by intense rainfall are one of the most dangerous post-fire hazards. The risk of floods and debris flows after fires increases due to vegetation loss and soil exposure.
Debris flow - SpringerLink
Debris flows are a significant geomorphological and sedimentological agent in a wide range of geologic and climatic settings. Subaerial debris flows pose a natural hazard than can cause fatalities, damage structures, and diminish land productivity.

2024年3月21日 — Watch for debris flows and other fast-moving landslides that pose threats to life: If you are near a wildfire burn area, sign up for emergency alerts and pay attention to weather forecasts for the burn area. Listen and watch for rushing water, mud or unusual sounds.
10.6: Debris Flows - Geosciences LibreTexts
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
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).
