| 摘 要： | The study for debris flow kinetic characteristics can not be approached byexperiments due to their complexity and distransparency,etc.This paper is a picture of debrisflow kinetic characteristics based on the natural debris flow observation and experiments.Thekinetic characteristics of viscous debris flow are obtained by radar veloeimeter and ultrasoniclevel meter in jiangjia ravine.From those,the following are suggested:in natural channel,debris flow can be classified as three kinds of type:strong turbulent debris flow;turbulent debrisflow;weak turbulent debris flow:meanwhile the Reynolds number(Re)is chosen as an indexfor the classification.
