Short summary
The purpose of our research is to understand the mechanisms that determine the mobility of granular flows of rock fragments. Since rock avalanches and pyroclastic flows are too dangerous to be studied at close range, we use numerical simulations and laboratory experiments. We focus on the fundamentals upon which new numerical models will be built to predict the behaviors of natural flows. These fundamentals include the effects of grain size, flow volume and channel width.
