Debris Flow Assessment in the Gaizi-Bulunkou Section of Karakoram Highway

Frontiers in Earth Science, 2021
Highways frequently run through the flow and accumulation areas of debris flow gullies and thus are susceptible to debris flow hazards. Assessing debris flows along highways can provide references for highway planners and debris flow control, emergency ...

Variable selection based on entropic criterion and its application to the debris-flow triggering [PDF]

, 2006
We propose a new data analyzing scheme, the method of minimum entropy analysis (MEA), in this paper. New MEA provides a quantitative criterion to select relevant variables for modeling the physical system interested. Such method can be easily extended to

Comparison of measurement methods of the front velocity of small-scale debris flows [PDF]

, 2015
Debris flow is a gravity-driven process, which is characterized by a travelling dense surge including large boulders, and it is followed by a more fluid tail.

Bed scour by debris flows: experimental investigation of effects of debris‐flow composition [PDF]

Earth Surface Processes and Landforms, 2016
AbstractDebris flows can grow greatly in size by entrainment of bed material, enhancing their runout and hazardous impact. Here, we experimentally investigate the effects of debris‐flow composition on the amount and spatial patterns of bed scour and erosion downstream of a fixed to erodible bed transition. The experimental debris flows were observed to

A Case Study on the Closed-Type Barrier Effect on Debris Flows at Mt. Woomyeon, Korea in 2011 via a Numerical Approach

Energies, 2021
Debris flows are capable of flowing with high velocities and causing significant economic and infrastructural damage. As a hazard mitigation measure, physical barriers are frequently installed to dissipate the energy of debris flows.

Analysis on the mechanism of debris flow in Meilong valley in Danba County on June 17，2020

Zhongguo dizhi zaihai yu fangzhi xuebao, 2022
A destructive debris flow broke out in Meilong gully, Danba County, on June 17, 2020, discharging almost 427000 cubic meters of solid material, triggering a disaster chain consisting of debris flow, debris-flow dam, outburst flood, and landslide, forcing

Induction of chromosome damage by ultraviolet light and caffeine: Correlation of cytogenetic evaluation and flow karyotype [PDF]

, 1982
Asynchrononously growing cells of a M3-1 Chinese hamster line were ultraviolet (UV) irradiated ( = 254 nm) with UV fluences up to 7.5 J/m2. After irradiation, cells were incubated with or without 2 mM caffeine for 20 hr, then mitotic cells were selected ...

The distribution of debris flows and debris flow hazards in southeast China [PDF]

WIT Transactions on Engineering Sciences, 2010
Debris flows commonly occur throughout southern China, posing a hazard to people, property and infrastructure. Although debris flows occur more frequently and with greater magnitude in mountainous southwest China, where they have been studied extensively, their impacts on society are greater in southeast China, where population densities and land use ...
