Data from large‐scale debris‐flow experiments are combined with modeling of particle‐size
segregation to explain the formation of lateral levees enriched in coarse grains. The …

A depth-averaged µ(I)-rheology for shallow granular free-surface flows Page 1 J. Fluid Mech.
(2014), vol. 755, pp. 503–534. c Cambridge University Press 2014 doi:10.1017/jfm.2014.450 …

We develop a full two-dimensional Coulomb-viscoplastic model and apply it for inclined
channel flows of granular materials from initiation to deposition. The presented model …

This paper describes the implementation of topographic curvature effects within the RApid
Mass MovementS (RAMMS) snow avalanche simulation toolbox. RAMMS is based on a …

In the present paper, flows of granular materials impacting wall-like obstacles down inclines
are described by depth-averaged analytic solutions. Particular attention is paid to extending …

Debris flows can spontaneously develop regular large-amplitude surge waves that are
interspersed by periods in which the channel fill is completely stationary. These are …

Snow avalanches and other hazardous geophysical granular flows, such as debris flows,
lahars and pyroclastic flows, often impact on obstacles as they flow down a slope …

Sedimentary structures deposited from dilute pyroclastic currents are largely dominated by
the products of metre‐scale dune bedforms containing backset lamination. Since the first …

The shapes of standing jumps formed in shallow granular flows down an inclined smooth-
based chute are analysed in detail, by varying both the slope and mass discharge …

Particle-size segregation can have a significant feedback on the bulk motion of granular
avalanches when the larger grains experience greater resistance to motion than the fine …
