Rheology of debris flow materials is controlled by the distance from jamming. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance Debris flows are fast-flowing and dangerous slurries of soil and water that often form when intense rainfall soaks hillsides burned by wildfire.

Transition of a small Himalayan glacier lake outburst flood to a giant transborder flood and debris flow. [PDF]
Sci Rep, 2022 Glacial lake outburst floods (GLOFs) are a great concern for the Himalaya, as they can severely damage downstream populations and infrastructures. These floods originate at high altitudes and can flow down with enormous energy and change the terrain’s ...

Development of an open source Debris Flow Simulator for “Sabo” (DFSS) [PDF]
E3S Web of Conferences, 2023 We report the development of an open source “Debris Flow Simulator for Sabo” (DFSS). DFSS consists of three models corresponding to three geomorphological regions (mountain hillside slopes, mountain-to-plain river channels, and lower plains).

Effects of debris-flow and bed composition on erosion and entrainment [PDF]
E3S Web of Conferences, 2023 Erosion and entrainment of material by debris flows determine debris-flow volume growth and therefore hazard potential. Recent advances in field, laboratory, and modelling studies have distilled two driving forces behind debris-flow erosion; impact and ...

Experimental study on the effects of local sediment accumulation on a debris flow surge in a steep channel [PDF]
E3S Web of Conferences, 2023 Debris flow surges can terminate in a steep channel of > 15°. However, the termination process and mechanisms remain unknown. This study conducted small-scale flume experiments to investigate the effects of local sediment accumulation on debris-flow ...

Deriving Debris‐Flow Dynamics From Real‐Time Impact‐Force Measurements
Journal of Geophysical Research - Earth Surface, 2023 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 measurements and field observations of debris flows recorded by a ...
