| 摘 要： | 结合长江中下游监利河段弯曲分汊情况拟定出概化模型,通过对江心洲从右到左的演变实验数据分析,得出了在同级流量时,随着洲头及边滩的推移,江心洲对水流的作用:产生的横向环流和环流强度分布规律,环流的存在引起水流的循环和泥沙的横向搬运作用,对于弯曲型河段的造床过程起作用,为解决弯曲分汊河段浅滩的演变机理等一系列问题提供一定的理论依据.

| Abstract: | In this paper,within the section of the Yangtze River in Jianli,a curve and branch generalized model is determined through a river island analysis of the experiment data obtained at the same level flow,with the continent over the beach head,The role of water river island: circulation and circulation generated by horizontal intensity distribution of the circulation flow caused by the presence of the horizontal circulation and sediment transport function can solve the curved branching channel.The mechanism of... |
