南渡江出海口横沟河段分流比研究

Study on Flow Distributary Proportion of Henggouhe Channel at Nandujiang River Mouth

分析不同分流比时的设计水面线,通过南渡江河口段分流口位置的设计水位确定较合适的分流比为8∶3。将该分流比情况下得到的分流口位置的设计水位与已有研究成果相比,可知本文计算出的设计水面线较为合理,能满足南渡江河口段整治的需要。

Based on the former research results and the channel actual stare, the design water surface curve for each flow distributary proportion is calculated using the different assumption distributary proportion. The best ratio of distributary proportion is eight to three by design water level at the distributary mouth. The design water level at the distributary mouth is compared and analyzed with the former study results. The result indicates that the obtained result in the paper is reasonable, and it may satify the practical need of Nandujiang River mouth channel regulation.
