东江水流传播时间简要分析

Analysis of the Water Flow Propagation Time of Dongjiang River

为给东江防洪、供水调度提供技术依据,该文采用历史资料统计分析、放水试验、代表河段水力学模型计算等方法,对东江干流及主要支流西枝江的洪水、枯水水流传播时间进行了系统分析。得到了东江洪水、枯水的水流传播规律,揭示了洪水和枯水水流传播之间相关关系,明确了梯级对水流传播的影响。

In order to provide technical basis for flood control and water supply operation of Dongjiang River,This paper systematically analyzes the propagation time of flood and dry water flow in Dongjiang River and its main tributary Xizhijiang River by statistical analysis,water discharge test and hydraulics model.The regularity of water flow transmission of flood and dry water in Dongjiang River is obtained,and the correlation between flood and dry water flow transmission is revealed,and the influence of cascade hydropower stations on water flow transmission is clarified.
