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 …

Flexible barriers are a promising tool for protection against extremely rapid landslides such
as debris flow and debris avalanches. With landslide impacts of any size, the total force …

Flexible barriers undergo large deformation to extend the impact duration, and thereby
reduce the impact load of geophysical flows. The performance of flexible barriers remains a …

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

Both the solid and fluid phases in a debris flow vitally influence the impact dynamics against
a rigid barrier. However, previous numerical and analytical models commonly adopt an …

A case study on an open hillside landslide impacting on a flexible rockfall barrier at Jordan
Valley, Hong Kong is presented in this paper. The landslide occurred sometime in June …

The impulse load of boulders at the front of debris flows is critical to the design of structural
defense measures, which are commonly constructed on hillsides to mitigate landslide risk …

Flexible barriers are an effective type of mitigation measure against debris avalanches in
valleys and can affect the kinetic energy and mass of debris avalanches. To investigate the …

Our limited understanding of the mechanisms pertaining to the force exerted by debris flows
on barriers makes it difficult to ascertain whether a design is inadequate, adequate, or over …

Landslide risks arising from boulder falls and debris flows are commonly mitigated using
rigid and flexible barriers. Debris–barrier interaction is a complicated process, so current …
