| Abstract: | Based on field survey of the sedimentary structures of ancient debris flows in Yaodian valley, we analyzed the causes and described the sedimentary characteristics. Then the natural density of debris flow activity was calculated using the gravel and fine particle content of ancient debris flows＇ samples in different spots to define the type. Finally the formation mechanism of debris flows, and the impact to human activities were discussed. |
