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 …

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 …

Natural terrain landslides are mainly triggered by rainstorms in Hong Kong, which pose
great threats to life and property. To mitigate landslide risk, building a prediction model …

In mountainous terrain, landslide debris is a common occurrence around the world that can
potentially result in catastrophic consequences to downstream residents and facilities …

Boulders entrained in debris flow induce high impact forces on a rigid barrier. In current
design practice, the concentrated load from boulders is estimated using the Hertz equation …

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

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 …

Structural countermeasures such as slit dams and check dams are widely installed in
mountainous regions to mitigate debris-flow hazards. However, current approaches adopted …

In mountainous areas, channelized rock avalanches swarm downslope leading to large
impact forces on building structures in residential areas. Arrays of rock avalanche baffles are …

Debris flows are one of the perilous landslide-related hazards due to their fast flow velocity,
large impact force, and long runout, in association with poor predictability. Debris-flow …
