Debris flows occur in mountainous areas characterized by steep slope and occasional
severe rainstorms. The massive urbanization in these areas raised the importance of …

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 …

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 …

Runup of debris flows against obstacles in their paths is a complex process that involves
profound flow deceleration and redirection. We investigate the dynamics and predictability of …

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

Run-up of granular debris flows against slit dams on slopes is a complex process that
involves deceleration, deposition, and discharge. It is imperative to understand the run-up …

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

A deflector is a structure installed at the crest of a rigid barrier to prevent the over-spilling of
debris flow from damaging the downstream infrastructures and human lives. Despite its clear …
