Surface water and ground water always influence each other in nature, both of which constitute an organic unity. Because of the gradual understanding of the impact of this interaction, surface water and groundwater coupled models are mostly used for the simulation and analysis of the process and its impact. This article concludes the research progress and focuses the coupled system of surface and subsurface flow to describe. However, the interaction between surface water and groundwater is still hot and difficult in today's research, because the interaction law is very complex. The application of MODHMS which is a coupled model for evaluating surface and subsurface flow is used for simulating non-point source pollution. Advantages and disadvantages of the model are analyzed for the future hydrology application.
