In this paper, the advances in researches on frozen soils and hydrology in cold regions are reviewed. On the basis of analyzing the seasonal freezing and thawing hydrologic process and properties of soils, the snowmelt runoff models, infiltration characteristics and forecasting models are summarized systematically, and the hydrologic models of non-frozen soil regions are improved in order to apply to the cold regions for quantitatively studying the water movement in frozen soils and modeling. Finally, it is suggested for the further study that to develop more realistic hydrologic and water conservancy models; to collect and monitor field experiment data and to determine the parameters in models; and to combine perfectly the hydrologic models and water migration models in frozen soil regions.
