Landslides are serious geohazards that occur under a variety of climatic conditions and can
cause many casualties and significant economic losses. Centrifuge modelling, as a …

The gravitational field affects the evolution of multiphase media, such as rocks, soil, and
alloy melts. Hypergravity increases the body force of matter, enhancing the driving force of …

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 centrifuge modeling of the impact dynamics of high-speed granular flows is important for
understanding debris–barrier interactions. However, it remains challenging owing to the …

Debris-flow impact against rigid obstacle involves instant redirection of flow velocity and
elevation of flow depth, and could serve as a stringent approach for verification of the two …

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 …

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 …

Flow-type landslides, such as debris flows and rock avalanches, erode soil bed material as
they flow downslope. The eroded material increases the volume of a landslide, and thus, its …

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

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 …
