Debris-flow disaster has caused large casualties and tremendous economic loss. Check
dams, flexible barriers, silt dams and baffle arrays are most used disaster prevention …

This study investigates the interaction between dry debris flows and a rigid barrier through
discrete element modeling (DEM) of flume tests. The debris materials were modeled as an …

The dynamics of debris flows are fundamentally governed by the interaction between the
solid and fluid phases. However, current approaches used to estimate impact load treat …

Baffles and check-dam systems are often used as granular flow (rock avalanches, debris
flows, etc.) control structures in regions prone to dangerous geological hazards leading to …

Slit-type barriers serve as active countermeasures against debris flow. However, the
dynamic interaction between debris flows and slit-type barriers is extremely complicated. To …

Structural countermeasures such as rigid and flexible barriers are commonly installed in
mountainous regions to intercept mass-wasting processes. Without sufficient and reliable …

Light-weight flexible steel net barriers catch coarse debris, but let some of the fine material
and water pass through the net. They are difficult to design so that they can withstand the …

Understanding the interaction between complex geophysical flows and barriers remains a
critical challenge for protecting infrastructure in mountainous regions. The scientific …

Flow-structure interaction has raised significant attention among geotechnical community
because it is important for prevention of high-speed flowing geo-disasters. Physical …

Multiple barriers are commonly installed along predicted geophysical flow paths to intercept
large flow volumes. The main criterion for multiple-barrier design is volume retained. The …
