| 摘要: |
| 对黄河河口现行清水沟流路范围内不同汊河的形成、演化及其特征进行了梳理总结，围绕汊河不同运用方案的影响效应进行了论证分析。研究表明：现行清水沟流路范围内的汊河运用方案不适用于多汊河轮流行河模式、同时行河与轮流行河联合模式和同时行河模式，而采用单一汊河轮流行河模式可以充分发挥海洋输沙动力，保证河口海域向外海的较大输沙量，对延长清水沟流路使用年限更有利，更为科学和经济合理。在现行清8汊河达到改道标准后，应优先使用老河道汊河，该方案不仅有利于未来海岸线的均衡发展，而且更有利于延长清水沟流路的使用年限。 |

| Abstract: |
| This paper summarizes the formation, evolution, and characteristics of different branching rivers in the current Qingshuigou channel in the Yellow River estuary; further, it demonstrates and analyzes the effect of different branch river operation schemes. The results show that neither the multi-river-running-in-turn mode, the parallel-running mode, or the combined mode is suitable for the Qingshuigou channel, while the single-river-running-in-turn mode is the most scientific, economical, and reasonable one. This mode can make full use of marine sediment transport energy, ensure a large amount of sediment transport from the estuary to the open sea, and is more beneficial to extend the life of the Qingshuigou channel. After the current Qing8 branch reaches the diversion criteria, the Old Branch river should be used first, which not only favors the balanced development of the future coastline but also extends the life span of the Qingshuigou channel. |
