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 …

Flexible obstacles are used to reduce the impact load exerted by granular flows. However,
grain-scale interactions between granular assemblies and flexible obstacles remain poorly …

Understanding the interaction between complicated geophysical flows and barriers remains
a critical challenge for hazards countermeasures in engineering design. In this study, the …

Even though dry granular flow can cause well-known impact hazards to retaining structures,
studies rarely have been conducted to determine the influence of particle-size segregation …

The gravitational flows of granular materials are omnipresent in industrial processes such as
handling and transportation of material and in natural events such as landslides, rock and …

Protective barriers provide crucial resistance against the impact of granular flows. However,
the adoption of characterized flow depth and velocity values in impact force estimation …

Rigid barriers are prevalent structure countermeasures for mitigating granular flow hazards
in mountainous areas. To reduce maintenance for barriers, a basal clearance is commonly …

Purpose–The purpose of this paper is to examine several calibration techniques that have
been developed to determine the discrete element method (DEM) parameters for slow and …

Coarse grains accumulate in geophysical flow fronts and have high solid fractions. Such
fronts may arch in slit structures such as baffles and slit dams, leading to the rapid trapping …

Understanding the interaction between complex geophysical flows and barriers remains a
critical challenge for protecting infrastructure in mountainous regions. The scientific …
