In Japan a large debris flow or landslide is called yamatsunami , literally mountain tsunami. Ancient debris flow deposit at Resting Springs Pass, California. Debris flows are accelerated downhill by gravity and tend to follow steep mountain channels that debouche onto alluvial fans or floodplains.
The risk of debris flow — a type of landslide that can cause severe damage — around recently burned areas in Los Angeles County is growing as this weekend's rains approach. There is now a 10% ...
Mudflows and debris flow are types of landslides. "The most likely outcome is for no significant debris flows, but there's a high-enough chance to definitely amplify the message that it's there ...
Landslides, also known as landslips, or rockslides, [3] [4] [5] are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. [6] Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from ...
A landslide, also called a landslip, [10] is a relatively rapid movement of a large mass of earth and rocks down a hill or a mountainside. Landslides can be further classified by the importance of water in the mass wasting process. In a narrow sense, landslides are rapid movement of large amounts of relatively dry debris down moderate to steep ...
“The next monster is debris flow and landslides,” said Farshid Vahedifard, a professor in the civil and environmental engineering department at Tufts University.
Debris flow channel scoured out by the passage of a debris flow. A flow is a spatially continuous movement in which surfaces of shear are short-lived, closely spaced, and usually not preserved. The distribution of velocities in the displacing mass resembles that in a viscous liquid.
During a debris flow, water not only picks up mud as it rapidly flows downhill but also rocks, branches, trees and sometimes boulders. This is considered a type of shallow landslide. Debris flows ...
