Debris flows occur in mountainous areas characterized by steep slope and occasional
severe rainstorms. The massive urbanization in these areas raised the importance of …

Multiple debris-resisting barriers have been commonly used worldwide to mitigate debris
flows in drainage lines. However, a well-developed methodology to assess the mobility of …

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 …

A full understanding of the interaction mechanisms among flow-like landslides and impacted
protection structures is still an open issue. Although several approaches, from experimental …

Extreme rainfall-induced debris flow can be catastrophic to an urban area, and installation of
slit-type barriers can prevent such damage while minimizing negative impact on …

Flexible barriers trap large particles and boulders in debris flow but allow slurry and small
particles to pass through. Field tests and real cases indicate that a certain amount of slurry …

We use small-scale modelling to estimate the impact ofrce of debris flows on erosion control
dams (ECD) and ring nets. The results indicate that the viscoelastic debris flows produced …

Defense structures are commonly constructed on the upstream side of bridge piers to
mitigate the impact of potential debris-flow events. In this study, field investigations were …

The magnitude of debris-flow impact force with soil layer entrainment was analyzed using a
coupled Eulerian-Lagrangian (CEL) technique in ABAQUS. To consider the entrainment of …
