黄河下游悬河温县段河水位变化对侧渗的影响研究

Study on Groundwater Recharge of the Lateral Seepage in Wenxian Section of the Aboveground Segment of the Yellow River Downstream

黄河水资源是沿黄地区经济和社会发展的重要限制因子。由于黄河在下游河段形成地上悬河,黄河的侧渗成为该地区地下水的重要补给源。通过分析温县的含水层结构,建立了地下水的二维模型,应用feflow软件对温县的浅层地下水进行了模拟,并对不同黄河水位变化情况下的黄河侧渗量进行了模拟计算,认为随着黄河水位的变化,将会引起两岸地下水位的相应变化,这为该县的水资源管理提供了依据。

It＇ s the limited factor to the society and economic in the downstream area of the Yellow River. As an aboveground river, the lateral seepage of the Yellow River is the important recharge. The paper analysis the aquifer fabric, a two dimension model was built up using the software-reflow, and simulated the lateral seepage of the Yellow River at the different river level, the result reveal the groundwater level is run up when the river level became higher,and vice versa. It＇s the great useful for the water resource manage of the county.
