The interaction between groundwater and streams is very important in water science. In this paper, the authors reviewed the development of the interaction of streams and groundwater in the following aspects. a. The principle of recharge and discharge between groundwater and streams was analyzed by investigating the changes in water flow and water table. b. Some factors that effect the interaction of groundwater and streams were illustrated, such as topography, hydrogeology, climate and other anthropogenic influence. c. Some study methods were assessed, such as field and laboratory experiment, dynamic data analysis, water chemistry. d. The development of modeling the interaction of aquifer and streams was discussed. The authors pointed out that some research fields will become frontiers and of concern, such as ecological significance of interaction of groundwater and stream, anthropogenic influence and hydrogeology of hyprotheic zone, multi-disciplinary communication and cooperation.
