Coarse grains accumulate at granular flow fronts and must be considered when studying granular flows impacting barriers. Experimental studies often use instrumented barriers …
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 …

The destructive granular flow hazards can be mitigated by intercepting the solid particles using protective barrier in the flow paths. Changes in the performance of barrier are usually …
Conservative estimates of forces from debris flows on barriers are computable using the 'free field approach', assuming that flows are channelised until impact. However, this approach …
Rapid soil–boulder mixed flow commonly occurs in steep mountainous regions and has the potential to damage critical infrastructures. Baffles are typically used as flow-impeding …

Arrays of baffles are widely used to prevent and mitigate granular flows (eg, debris flows and landslides) in mountainous areas. A thorough understanding of the decelerating effect and …
Debris flows moving at high speed along valleys can bring disastrous consequences to downstream regions. Structural countermeasures are commonly installed along anticipated …
