Debris flows are among the most catastrophic natural phenomena, attracting the interest of
researchers, engineers and government agencies. The complexity of the physical process …

Geomorphic mass flows are often complex in terms of material composition and its evolution
in space and time. The simulation of those hazardous phenomena would strongly benefit …

A rational rheology model is critical for the numerical simulation of debris-flow behavior. The
Bingham model commonly used in many current studies has failed to simulate the shear …

Extraction of physical quantities such as flow depth and velocities, is one of the major
purposes of geophysical flow numerical modeling and critical for estimating consequent …

Flexible, slit, and rigid barriers are common countermeasures to mitigate natural
geophysical mass flows, but presently, quantitative comparisons of their performance are …

Geophysical mass flows impacting flexible barriers can create complex flow patterns and
multiway solid‐fluid‐structure interactions, wherein estimates of impact loads rely …

The incompressible-rheology with low-Stokes-number experiments, which incompressible
models fail to describe. The combination of granular rheology, pore pressure and drag …

Climate change is resulting in more frequent rainstorms and more rain-induced debris flows
in mountainous areas. The prediction of likely hazard zones is important for debris flow risk …

Slit dams are widely used for managing multiphase geophysical flows with diverse
objectives. However, quantitatively linking dam configurations and flow properties to design …

An Eulerian-Eulerian two-phase model based on a collisional-frictional law for the granular
stress is proposed for the description of underwater granular flows and is applied to the …
