【 摘 要 】

This paper presents a debris flow hazard prediction procedure for different prediction stages. At preliminary prediction stage, Melton ratio (R) is applied to predict the debris flow basing on its linear connection with debris flow occurrence frequency during Typhoon Rananim. At detailed prediction stage, a factor-combined model is brought in to predict the hazard degree. The prediction procedure is applied to 14 typical debris flows in southeast mountain area in Zhejiang Province, the results conform to the characteristics of typhoon-triggered debris flows in study area.
