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 …

Boulders entrained in debris flows can often generate destructive impact forces and cause
damages to rigid barriers. In this study, a large-scale numerical flume model based on the …

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 …

Dam-break flows may change into debris flows if certain conditions are satisfied, such as
abundant loose material and steep slope. These debris flows are typically characterized by …

Rigid barrier deflectors can effectively prevent overspilling landslides, and can satisfy
disaster prevention requirements. However, the mechanisms of interaction between natural …

Debris flows are one of the perilous landslide-related hazards due to their fast flow velocity,
large impact force, and long runout, in association with poor predictability. Debris-flow …

Drainage channels with step-pool system are widely used to control debris flow. The
blocking of debris flow often gives rise to local damage at the steps and baffles. Hence, the …

Debris flows are rapid gravity-driven unsteady flows of highly concentrated mixtures of water
and solid particle material, destroying numerous mountain building structures and traffic …

In nature, when hazardous geophysical granular flows (eg a snow avalanche) impact on an
obstacle as they stream down a slope, rapid changes in flow depth, direction and velocity …

Rapid granular flows are one of the most catastrophic geo-disasters frequently encountered
in mountainous areas. The baffle structure has been demonstrated to be an effective …
