Flexible barriers have been increasingly used worldwide for mitigating natural hazards
involving various geophysical flows. The analysis and design of flexible barriers need to …

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 …

Changes in basal fluid pressure and normal flow depth in 2-phase granular mass flows, the
equivalent coefficient of friction and the equivalent coefficient of friction between gravity …

The process of a dry granular flow impacting a rigid retaining wall was systematically studied
using three types of granular materials with different physical parameters. The experimental …

Debris flow normally occurs after heavy rains in mountainous regions with multiple surges.
Flexible barriers are installed in torrents to intercept debris flows in an early stage. For the …

Soil cushion layers are commonly paved in front of protection structures to avoid the direct
impact of rockfall and debris flow. This study is devoted to investigating the influence of …

Understanding the fundamental dynamics of interaction between multi-phase geophysical
flows and engineering structures is crucial for mitigating geophysical hazards. Specifically …

Flexible ring net barriers have become increasingly popular in practical mitigation of debris
flow worldwide. Systematic assessments of their response and performance subjected to the …

This study investigates the interaction between dry debris flows and a rigid barrier through
discrete element modeling (DEM) of flume tests. The debris materials were modeled as an …

Flexible barriers may be installed upstream in debris flow channels to reduce entrainment of
bed material. Simulating both the entrainment and the impact on a barrier by the same …
