摘要
流域内的河流与地下水之间存在着密切的水力联系,为研究一次洪水过后河流与沿岸地下水之间关系,在分析其水文地质条件基础上,建立河流与地下水之间数学模型,求解了潜水含水层水位、沿岸侧向单宽流量、渗流速度等,并以淮河流域的王家坝站附近地下水为例进行计算,分析了其地下水动态变化特征,讨论了渗透性与给水度对河流回水过程中对潜水的影响,研究结果为地下水与地表水关系应用具有一定参考价值。
It＇s well known that there is a close hydraulic connection between the river and the groundwater in the watershed. In order to study the relation,a mathematical model is established based on the analysis of the hydrogeological conditions. The model discusses the water level of the unconfined water,per unit discharge and seepage velocity,etc. Moreover,taken the groundwater in Huaihe Wangjiaba for example,the dynamic characteristics of groundwater has been analyzed,and how permeability and specific yield having influence on the groundwater condition near the river is discussed. The research results are valuable for the application in the relationship between groundwater and surface water.
