松滋口分流及其对芦家河河势影响研究

Study on effects of Songzi bleeder diversion on fluvial evolution of Lujia river

依据实测资料 ,分析了松滋河口门河段的河床冲淤及水位流量关系、松滋口分流对芦家河河势变化的影响 ,提出了根据枝城站水位流量与新江口水位流量关系推求松滋口的分流量的方法 ,预估了三峡水库运用对松滋河分流及河床冲淤的影响 ,为芦家河河段进行数学模型计算及物理模型试验提供了边界条件 .

According to the measured data the bed silting or erosion of the Songzi bleeder entrance region and relations between water levels and discharges in the Songzi beeder, and effects of the Songzi bleeder diversion on fluvial evolution of the Lujia river, are analyzed. The way of inquiring into the Songzi bleeder diversion discharge based on relations between water level and discharge in Zhicheng and Xinjiangkou is presented. The Songzi river diversion and silting or erosion after completion of the Three Gorges Project is predicted. The results provided boundary condition for mathematical model and physical model of the Lujia river.
