数字孪生流域水文映射研究与实践OA

To investigate the construction contents and characteristics of hydrological mapping,the Dongwen River Basin was selected as a pilot basin to carry out research on hydrological mapping technologies and the applications of the"Four Pre"system.The research included the construction of a basin data baseplate for hydrological mapping,the development of a distributed hydrological model,research on hydrological-hydrodynamic coupling technology,and the development of the"Four Pre"application for hydrological mapping in a digital twin basin.The application of the distributed hydrological model enabled more refined and accurate simulation of basin hydrological processes.The coupling of the distributed hydrological model and the hydrodynamic model allowed more objective simulation of river flood routing processes.The"Four Pre"application for hydrological mapping in the digital twin basin covered key links of hydrological operations,including monitoring,forecasting,and early warning,providing support for and enhancing practical hydrological work.Through the research and practice of hydrological mapping in the Dongwen River digital twin basin,the construction contents of hydrological mapping have been preliminarily outlined and relevant technical achievements have been obtained.
