Abstract: Hydrological system is a complex system with many uncertain factors. These factors are not conductive to the accurate simulation and prediction of hydrological processes. Thus more and more people focus on the uncertainty analysis methods for the hydrological systems to improve the reliability of calculations. In this paper, we summarized the researches and the applications of the uncertainty analysis methods for hydrological systems. Based on the review, we introduced their mathematical principles, operational procedures and status of applications. Furthermore, the key tasks in the future were put forward, including uncertainty analysis of the mechanism of hydrological circulation and hydrological processes in combination of various methods.

Key words: hydrological system, method, uncertainty analysis
