- •
We investigate dynamics and transport mechanism of Wenjiagou Creek rock avalanche.
- •
Dynamic course is divided into three segments: the failing, the falling and the flow.
- •
Structure of the deposit was determined by grain-size distribution analysis.
- •
Ring-shear tests were conducted to simulate the shear between grains within debris.
- •
Shear resistance between grains decreases due to pervasive fragmentation.
