利用等效水力传导系数在地下水与地表水交互影响模拟中的应用

Application of Equivalent Hydraulic Conductivity in Surface Water and Groundwater Interaction

在滨海地区的环境管理工作中,地表水—地下水交互影响的重要性日益凸显。一方面在湿地系统的研究中,交互影响对地下水系统有着巨大的影响;另一方面,在河流——地下水系统中,大尺度管理模型的建立也是一个难题。因此,将等效水力传导系数的概念引入环境管理之中以解决这些问题。等效水力传导系数的推导过程是基于明渠流曼宁公式建立的,完成地表水系统与地下水系统的统一。最后,以抽水井管理为例,对该方法进行了演示。

The interaction between surface water and ground water is getting more important in environmental management,especially in sea coastal area.In wetland system,the interaction brings great impact to the groundwater system.In addition,the interaction is also a difficulty in large scale environmental management.The concept of equivalent hydraulic conductivity is introduced into environmental management to copper with the problems.The equivalent hydraulic conductivity is induced from open channel Manning equation to fulfill the unification numerical simulation of both surface water system and groundwater system.At last,an example of pumping well is give to illustrate the application of the method in environmental management.
