Debris-flow deposition: effects of fluid viscosity and grain size
Debris 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 ...
