Abstract: The progress of digital technologies brings new opportunities for improving the management capacity of the watershed. Since 2021, the China Ministry of Water Resources (MWR) has promote the construction of digital twin watershed in China. For the flood defense, the China MWR requests the local decision-maker to have integrated flood management based on the catchment scale and to set up the system consisted with “4 advance” process including forecast, early warning, rehearsal and plan. After several years of discovering and practicing, the concepts, strategies and technologies of implementation of digital twin on large catchment scale becomes more and more mature. Many application within watershed scale have been set up and operationally working in the catchment management. By systematically reviewing the digital twin applications in 7 large catchments of China, this study has presented the achievements of China in last several years and gave an expectation of the future digital twin development in China.
