Abstract： The digital twin river is an inter-response relationship constructed between natural and manage⁃
ment elements of a river， which is developed based on data-platform that integrates multi-source informa⁃
tion such as spatial data， meteorological， hydrological， environmental data etc.， using hybrid models that
coupling physically-based mathematical models with data-driven approaches such as machine learning and
knowledge graph， to realize the real-time mirroring of the whole process of water flow， information flow，
application flow and value flow of the river， therefore to provide technical support for river management
and the high-quality development of the river basin. Taking the application of flood management in the
Changjiang River Basin as an example， aiming to realize the functionalities of river simulation， forecast
and early warning，intelligent water engineering regulation，dynamic flood risk assessment，and system con⁃
struction，the paper presents the framework for developing the digital twin river and its key technologies in⁃
cluding the construction of data， models， intelligence and platform. The research results have been applied
in the construction of the digital twin Changjiang River，and has obtained the complete processes for the in⁃
telligent regulation of engineering works for flood management，including“flood forecasting-early warning-re⁃
hearsals-pre-planning”，and has provided technical support in 2020 the basin-scale flood management. The
research results can provide demonstration and experience reference for the construction of digital twin river.
Keywords：digital twin river；joint regulation of engineering works；knowledge graph；regulation rules
