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 …

Particle shape plays a crucial role in determining the mobility and impact characteristics of
granular flows, yet analyses of the effects of particle shape are rare. In this study, three …

Baffle structure, a promising countermeasure in reducing the destruction power of rapid
granular flows, needs more investigation especially with focus on the physically based …

Multiple barriers have become popular to mitigate debris flows worldwide. Existing
guidelines only recommend the minimum spacing based on volume retention, and the …

Rock–ice avalanches that occur in cold alpine regions often cause widespread devastation
because of their high mobility and massive destructive potential. The protection structure …

Forests cover 39% of low-altitude mountainous areas globally, and they are considered
natural barriers against geophysical flows. Owing to the complexity of flows, the protective …

Granular flow are considered as the one of the most hazardous geological disasters in
mountainous area. Multi-slit structure including one or more slits could partially block the …

The design strategies for barrier structures against high-speed granular impacts are still
lacking, because the granular impact dynamics is poorly understood. We have investigated …

Granular flows are typical hazard in mountainous terrains. Slit structure has been shown to
be a successful mitigating strategy. However, the interaction mechanism between granular …

Dry granular flow induced by rock collapses and landslides is a typical disaster in
mountainous areas. Rock sheds are widely used as protective structures to shield traffic …
