Abstract On July 20, 2013, a landslide-induced debris flow occurred in Dujiangyan city,
China. Eleven houses were destroyed with more than 166 fatalities. Previous literature …

Large boulders can jam in constrictions, both in canyons and man‐made structures (eg, slit‐
dams). Boulder jamming occurs stochastically, and partially governs the outflow rate of …

Earth surface flows in nature, like debris flows and rock avalanches, have threatened
people's safety and infrastructure during past decades. Though grain size distribution (GSD) …

Structural countermeasures such as slit dams and check dams are widely installed in
mountainous regions to mitigate debris-flow hazards. However, current approaches adopted …

Rock-ice avalanches exhibit significant particle segregation driven by density and friction
differences between ice and rock. This study meticulously uncovers intricate segregation …

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 …

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 …

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

The peak pressure of a granular debris flow at low Froude conditions can be calculated with
knowledge of the stress anisotropy and the bulk density as well as the run-up height at …

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 …
