Advances in the Integr ated Sur face Water and Groundwater Model
地表水和地下水耦合模型研究进展

With the effects of climate change and large-scale human activities,interactions between groundwater and surface water become more and more complex and acute.So studying groundwater and surface water as a whole system is urgent now.There are many integrated surface water and groundwater models,and they are divided into different kinds according to different standard.This paper summarized the existing 16 major integrated surface water and groundwater models at home and abroad,and classified them into close coupling and loose coupling.SWATMOD,MIKE-SHE and MODBRANCH model are described in detail on their functions,structures,coupling methods and deficiencies.At last,key problems to be addressed such as conversion of temporal or spatial scale,soil moisture movement in heterogeneous soil,parameter uncertainty,interactions between stream and ground water are pointed out,and the paper concluded that a complicated system model combining all the components in water cycle is the a trend of integrated models' development in present.
