摘要
通过概化水槽试验,研究了流量过程对河型的影响。试验表明,不同的流量过程形成的河道形态不同;在适当的条件下,流量过程的改变将导致河型转化。河床组成与河谷比降直接影响流量过程的作用效果。大流量阶段在河道的演变过程中影响显著。
It's common of the change of discharges in rivers. Discharge process is also an important cause of the formation and transformation of channel patterns. By means of experimental study, different discharge processes may end with different river morphology, even can lead to channel pattern transformation. The discharge process influences the channel pattern based on the relationship between the flow and the river bed. The flood acts an important roll during the formation.
