A key mechanism by which geophysical flows evolve is mass exchange with the underlying
bed, either by entraining material from the bed, or by depositing material. Although it is …

This article examines the spatial and temporal behaviors of the dynamics of bedload
particles in water. We focus particularly on the fluctuations of particle activity, defined as the …

We report natural geophysical mass flows are among the most complex granular systems
and their dynamics are often modified by the presence of an interstitial fluid. Prediction of …

Flow-type landslides entrain mobile bed material, but the processes involved are diverse
and require systematic study. We perform direct numerical simulations using the open …

Natural geophysical mass flows are among the most complex granular systems and their
dynamics are often modified by the presence of an interstitial fluid. Prediction of their runout …

Intense bed load refers to a regime which is responsible of most of sediment transport in
torrents and rivers during floods. Even if restricted to uniform steady conditions and well …

Fluid-driven granular flows are widely found in nature and industry; however, understanding
their dynamics remains a challenge for geophysicists and engineers. A fluid flow imposed …

Bedload transport occurs when a bed composed of sedimentary grains becomes mobile in
response to the shearing by a flow of liquid. It shapes the landscapes of Earth and other …

Because bed load equations are nonlinear and because parameters describing the flow and
the bed can have large variance, different results are expected when integrating bed load …

A theoretically-based methodology is presented for the determination of bed load transport
from high-resolution measurements of bed surface elevations for steady-state or developing …
