AbstractDebris flows in mountainous regions are of great concern because they present a serious threat to the residents and infrastructures in downstream areas as a result of their long runout distances. However, the mechanisms of debris-flow runout are still unclear because of many factors influencing debris-flow mobility. This study focuses on two major factors, namely, particle size and slurry viscosities. A series of experimental model tests were conducted in a rectangular inclined flume connected to a final horizontal plain. Results reveal that the debris-flow mobility is significantly influenced by the slurry viscosities. The runout distance initially increases and then decreases as the slurry viscosities increase. Also, runout distance for debris flows contain large particle sizes is longer than that of debris flows contain small particle sizes. The depositional widths are almost unchanged in the experimental test, which suggests that the debris flows are constrained by the fixed channel boundaries. The results of this study can improve the understanding the behavior and the deposition features of debris flows. © 2019 Debris-Flow Hazards Mitigation: Mechanics, Monitoring, Modeling, and Assessment - Proceedings of the 7th International Conference on Debris-Flow Hazards Mitigation.
