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 …

In the context of two-dimensional models for complex geophysical surface flows such as
debris flows, muddy slurries, oil spills over land, hyperconcentrated floods, lava flows, etc …

Recently, depth-averaged shallow flow models have been adapted to modelling liquefied
lava flows, generally characterized by a marked temperature-dependent non-Newtonian …

The bedload transport system of equations, composed by the two-dimensional shallow
water equations for the free surface flow motion and the 2D Exner or bedload transport …

Different coupled systems for the shallow water equation, bed elevation, and suspended
load equation are proposed until this day. The main differences come from the physical …

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 …

Numerical simulation of unsteady viscous flow over variable topography under the influence
of temperature changes is a challenge. In order to apply the model to large domains with …

Among the geophysical surface processes, mud and debris flows show one of the most
complex and challenging behaviour for scientists and modellers. These flows consist of …

Shallow-type mathematical models are built in the context of free surface flows over the main
hypothesis that the flow layer depth is smaller than a relevant horizontal length scale. There …
