It is well recognised that the rheology of an interstitial fluid has profound effects on debris
flow dynamics. Existing design guidelines for multiple resisting barriers, however, do not …

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 …

ABSTRACT Hong Kong, Taiwan and numerous other areas around the world are vulnerable
to debris flows. A single rigid barrier is generally installed at the end of a potential flow path …

Flexible barriers trap large particles and boulders in debris flow but allow slurry and small
particles to pass through. Field tests and real cases indicate that a certain amount of slurry …

Debris flows carry enormous momentum as they surge downslope and could cause loss of
lives and damage to infrastructure. Structural countermeasures such as rigid and flexible …

Multiple barriers are usually installed to effectively mitigate large-volume debris flows.
Existing multiple-barrier design recommendations ignore the effects of solid–fluid interaction …

The destructive nature of debris flows is mainly caused by flow bulking from entrainment of
an erodible channel bed. To arrest these flows, multiple flexible barriers are commonly …

Multiple barrier system has become a widely adopted method to mitigate debris flows, which
consists of smaller barriers that progressively retain the debris to reduce the acceleration …

Multiple barriers with basal clearance are usually adopted in engineering practice to
mitigate large volumes of debris flows. This approach allows for sufficient discharge and …

The multiple-barrier mitigation strategy in the debris-flow source area is an effective
approach to inhibit debris-flow entrainment and scale amplification along the flow path …
