The impact angle is an important but understudied factor that exerts a significant control on the propagation of granular flows. To investigate the influence of the impact angle on the …
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 …
Curved seawalls remain one of the most widely adopted coastal-protection measure. A curved face redirects flow momentum and prevents waves from overtopping. Likewise, the …

The peak pressure of a granular debris flow at low Froude conditions can be calculated with knowledge of the stress anisotropy and the bulk density as well as the run-up height at …
Structural countermeasures such as rigid and flexible barriers are commonly installed in mountainous regions to intercept mass-wasting processes. Without sufficient and reliable …
