Abstract
After determining the thresholds value of sources identification and the parameters of propagation, the Flow-R was used to simulate the potential hazard range of Bayi Gully debris flow. Then the simulation results were evaluated using the confusion matrix. Finally, the susceptibility of Bayi gully debris flow was assessed. The results show: (1) The small catchment channels at the top of the gullies provide rich sources for debris flow, (2) The sensitive areas are distributed roughly within the range of 40 m on both sides of channels and account for 20.06% of the study area, (3) The very high areas are distributed in the center of the channels and account for 50.38% of the sensitive areas. The susceptibility gradually decreases from the center of the channel to both sides.
