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 …

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 …

Flexible, slit, and rigid barriers are common countermeasures to mitigate natural
geophysical mass flows, but presently, quantitative comparisons of their performance are …

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 …

In the design of multiple rigid barriers, the height of the first barrier governs the impact
dynamics of debris flow on the next barrier in a channel. However, current design …

Both the solid and fluid phases in a debris flow vitally influence the impact dynamics against
a rigid barrier. However, previous numerical and analytical models commonly adopt an …

The paper deals with the effects of artificial barriers on the dynamic features of unconfined
flows such as debris avalanches in coarse-grained materials. These phenomena are often …

Slit-type barriers, one of open-type barriers, are widely used as active measures to mitigate
potential risk and damage by debris flows, and those are designed and installed to reduce …

Quantitative understanding of the load–deflection mechanisms of a flexible barrier in
intercepting debris flows is critical for barrier design, but remains practically challenging due …
