摘　　要：河渠与地下水存在着复杂的水量与水质上的相互转化关系,数值模拟方法是定量研究二者相互转化的常用方法之一。现对河渠与地下水的相互关系进行综述,建立了一维明渠流和三维非稳定地下水耦合控制方程。分析了国外典型数值模拟软件在模拟河渠与地下水相互转化的特点。以BRANCH与MODFLOW耦合模型为例,对建模的数学原理及模型计算等进行了阐述,并结合该模型在美国佛罗里达州南部地区的应用对模型具体的运行进行了讨论。最后指出了耦合模型存在的不足及发展趋势。The mutual transformation of water quantity and quality between canal and underground water is complicated. Numerical simulation is one of the most popular methods in quantitative research of mutual transformation between canal and groundwater. The paper summarizes the mutual relations between canal and underground water and sets up the coupling control equation of one dimensional open-canal flow and three-di- mensional groundwater transient flow. The paper states the characteristics of the mutual transformation between canal and underground water with the typical foreign numerical simulation software. Meanwhile, taking the coupling model of BRANCH and MODFLOW for example, the paper also states the mathematic mechanism for the establishment of the model and the calculation with the model and discusses the operation of the model by connecting to the application of the model in the southern area of Florida, U.S. At last, the paper also points out the disadvantages and development in the future of the coupling model.
