TL;DR: In this paper, the authors use data from large-scale experiments to assess the entrainment of bed material by debris flows and find that entrainments are accompanied by increased flow momentum and speed only if large positive pore pressures develop in wet bed sediments as the sediments are overridden by debris flow.

TL;DR: In this article, data collected in 28 controlled experiments reveals reproducible debris-flow behavior that provides a clear target for model tests. But it is not clear how to explain the behavior of debris flows.

TL;DR: Experimental landslides triggered by rising pore water pressure moved at sharply contrasting rates due to small differences in initial porosity, and were arrested by pore dilation and attendant pore pressure decline.

TL;DR: This paper measured the surface velocity field and observed the sequence of deposition by seeding tracers onto the flow surface and tracking them in video footage, and constructed an empirical, three-dimensional velocity field resembling the experimental observations, and used this with a particle-size segregation model to predict the segregation and transport of material through the flow.

TL;DR: In this article, the authors used laser-assisted cartography to map the 3D morphology of rapidly moving granular avalanches, thereby providing high-resolution data for comparison with model output.
