Earth‐surface mass flows such as debris flows, rock avalanches, and dam‐break floods can
grow greatly in size and destructive potential by entraining bed material they encounter …

This review article provides an overview of dry granular flows and particle fluid mixtures,
including experimental and numerical modeling at the laboratory scale, large scale …

Scaling plays a crucial role in designing experiments aimed at understanding the behavior
of landslides, debris flows, and other geomorphic phenomena involving grain-fluid mixtures …

Predicting debris flow runout is of major importance for hazard mitigation. Apart from
topography and volume, runout distance and area depends on debris flow composition and …

The objective of this review is to examine how the concept of plasticity is used in
geophysical fluid dynamics. Rapid mass movements such as snow avalanches or debris …

Runoff during intense rainstorms plays a major role in generating debris flows in many
alpine areas and burned steeplands. Yet compared to debris flow initiation from shallow …

Analyses of mass and momentum exchange between a debris flow or avalanche and an
underlying sediment layer aid interpretations and predictions of bed‐sediment entrainment …

Understanding the impact forces exerted by debris flows is limited by a lack of direct field
measurements and validated numerical models. In this study, we use real‐time impact‐force …

Debris flows are typically a saturated mixture of poorly sorted particles and interstitial fluid,
whose density and flow properties depend strongly on the presence of suspended fine …

A theoretical model based on a depth-averaged version of two-phase flow equations is
developed to describe the initiation of underwater granular avalanches. The rheology of the …
