Mud/debris flows are among the most challenging gravity-driven flows in environmental and
geophysical processes. Natural muddy slurries and debris are solid-laden fluids where the …

Tailings dam breach modelling studies have received considerable attention recently due to
the rise in the number of tailings dam failures and catastrophic consequences caused by …

We conduct direct numerical simulations (DNS) to study the temporal and spatial
developments of the roll waves on a laminar sheet flow of Newtonian fluid. The DNS unveil …

Debris flows are classical two-phase flows that are greatly affected by bed sediment
conditions. However, the underlying mechanism remains uncertain from either a theoretical …

To accurately predict impact loads can ensure the safe operation of debris flow control
projects. The instantaneous impact process is usually considered in the calculation of the …

In this study, a robust non-Newtonian numerical model that can simulate coupled mudflow
and sediment transport processes is used to model downstream geomorphic changes …

We develop a multilayer model to study roll waves in mudflow of Herschel–Bulkley fluids
initiated by periodic and localized disturbance. Simulations are conducted of the temporal …

The paper theoretically investigates the stability properties of the dam-break wave of a fluid
with power-law rheology. Assuming the longwave approximation, a depth-averaged flow …

In this work, a novel 2D depth-integrated numerical model for highly sediment-laden shallow
flows over non-uniform erodible beds is presented, including variable density and exchange …

Mass movements such as debris flows and landslides differ in behaviour due to their
material properties and internal forces. Models employ generalized multi-phase flow …
