| 摘 要： | 运用一维、二维联算洪水演进模型，对长江干流螺山—汉口河段的洪水演进进行了模拟，分析了洪湖分蓄洪区的启用对该河段水位的影响，同时还模拟了洪湖分蓄洪区的洪水演进过程。计算结果表明，洪湖分蓄洪区的开启，能够有效地降低该河段的洪水位，从而减轻长江干流的防洪压力。计算结果可为洪湖分蓄洪区的合理启用提供科学的依据，为长江防洪调度提供参考。

| Abstract: | Flood routing from Luoshan to Hankou of the main stem of the Yangtze River and in Honghu flood diversion area are simulated by 1-D and 2-D flood routing model,and the effect of flood diversion by Honghu diversion zone to water level lowering of the Yangtze River is analyzed.The analysis result show that the operation of Honghu flood diversion zone can effectively reduce the water level of the Yangtze River and mitigates the flood control pressure of the river.The computational result can provide scientific ... |
