| 1. | By reading papers on debris flow ' s triggering and confluence , we know that if we consider debris flow ' s triggering and confluence as a whole system , its whole process have many critical characteristic situation . such as , critical slope grade , critical thickness of earth source , critical precipitation , critical runoff and critical velocity of flow 本文通过对泥石流产汇流研究现状的分析得知,泥石流的产汇流可作为一个系统来研究,泥石流产汇流过程具有一系列临界特征值,如:临界坡度、土源临界厚度、临界雨量、临界流量和临界流速。 |
