On the coordinated routine and emergency management of China's hydrology and water resources

China is a country facing water resources shortage in general and often coexists with droughts and floods. In recent years, the frequency of extreme hydrological events has been increasing, while the attenuation of water resources in the north became evident, the situation has turned out to be severe. On account of the hydrologic regimes in China, as well as the research practices on the coordinated routine and emergency management of hydrology and water resources in aspect of utilization of stormwater, strategic reserves of water resources, and water storage spaces, the paper promoted the concept of establishment of the coordinated routine and emergency management of China's hydrology and water resources. That is, combining routine management in the normal state with emergency management in the abnormal state base on the overall annual and interannual hydrological processes, to implement water resources management in the whole process of circulation of natural water cycle, so as to realize the integration of development and utilization of water resources, and flood control and drought relief, promote the efficiency of circulation of water cycle, and enhance the level of water security.
