Physical barriers are effective tools in the mitigation of landslide hazards. Numerous case
histories have been reported where flexible barriers have successfully contained debris …

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 …

The runup height and impact load of landslide debris are the key parameters for design of
debris hazard mitigation structures. However, the movement of obstacle (eg, deformation of …

This paper presents some preliminary numerical results concerning the interaction between
debris flows and defense barriers. Related simulations were carried out by employing a …

Flexible net barrier systems against shallow landslides or debris flows have to be designed
properly to withstand the expected dynamic loads. However, there are almost no generally …

Flexible rockfall barriers have been widely used to mitigate rockfalls and protect residential
buildings, railroads and highways from such natural hazard. Evaluation of the performance …

Debris flows often cause local damage to engineering structures by exerting destructive
impact forces. The debris-flow–deformable-barrier interaction is a significant issue in …

Boulders entrained in debris flow induce high impact forces on a rigid barrier. In current
design practice, the concentrated load from boulders is estimated using the Hertz equation …

This paper presents a unified modeling framework to investigate the impacts of debris flow
on flexible barriers, based on coupled computational fluid dynamics and discrete element …

Structural countermeasures such as rigid and flexible barriers are commonly installed in
mountainous regions to intercept mass-wasting processes. Without sufficient and reliable …
