Effective design of mitigation measures against debris flow hazards remains a challenging
geotechnical problem. At present, a pseudo-static approach is commonly used for the …

A new analytical model is proposed to estimate the peak impact pressure of debris flow
exerted on a rigid barrier. The new model consists of two terms, p= α 1 ρ 0 gh 0+ 0· 5 ρ 0 u …

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 …

A channelized debris flow is usually represented by a mixture of solid particles of various
sizes and water flowing along a laterally confined inclined channel-shaped region to an …

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 …

Our limited understanding of the mechanisms pertaining to the force exerted by debris flows
on barriers makes it difficult to ascertain whether a design is inadequate, adequate, or over …

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

The runup height and impact load of landslide debris are the key parameters for design of
debris hazard mitigation structures. However, the movement of obstacle (eg, deformation of …

Debris-flow impact load is one of the key parameters for design of engineering
countermeasures. The multiple-surge load model is a remarkable progress in estimating the …

Landslide risks arising from boulder falls and debris flows are commonly mitigated using
rigid and flexible barriers. Debris–barrier interaction is a complicated process, so current …
