BRIEF ANALYSIS ON THE DEVELOPMENT TREND OF DAGOU DEBRIS FLOW AND ITS PREVENTION AND CONTROL MEASURES

Terrain and geomorphology, water source condition and loose solid materials in the debris flow gully are analyzed based on Dagou debris flow. Formation condition and initiation mechanisms of the debris flow gully are discussed, and the development trend of the debris flow gully is predicted. Finally, appropriate prevention and control measures are proposed according to its damage characteristics.
