Debris flow and debris flood phenomena threat the life of thousands of citizens living in
mountain areas and endanger buildings and infrastructure worldwide. The assessment of …

Debris floods have been defined descriptively as mineral and organic sediment‐rich floods,
occurring in a steep channel and potentially destabilizing the streambed and banks. While …

Debris flows originating in the mountain cryosphere (DFMC) are one of the most globally
important, widely distributed mass flows (and natural geohazards) in mountain areas with a …

Debris-flow impact against rigid obstacle involves instant redirection of flow velocity and
elevation of flow depth, and could serve as a stringent approach for verification of the two …

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 …

Extraction of physical quantities such as flow depth and velocities, is one of the major
purposes of geophysical flow numerical modeling and critical for estimating consequent …

Large boulders can jam in constrictions, both in canyons and man‐made structures (eg, slit‐
dams). Boulder jamming occurs stochastically, and partially governs the outflow rate of …

Sediment transport in mountain streams occurs through different flow types that are
categorized in accordance with hydraulics and physical properties of a flowing material, and …

Surging debris flows are among the most destructive natural hazards, and elucidating the
interaction between coarse‐grained fronts and the trailing liquefied slurry is key to …

Debris flows are one of the most dangerous landslide types in mountainous regions. Their
destructiveness is strongly controlled by their high peak discharge, which can be orders of …
