Abstract:

As a pilot canal section of Ningxia’s twin digital platform for water scheduling，the Hexi Main Canal plays a critical role in water transmission and distribution within the Qingtongxia Irrigation District. This study focuses on the water resource scheduling process of the Hexi Main Canal，exploring methods to achieve scientifi c water resource scheduling in a digital twin scenario. By integrating digital twin technologies，the research establishes a comprehensive twin-based scheduling system that simulates and maps the physical world. This system utilizes technologies such as multi-source heterogeneous twin data platforms，visualization models，one-dimensional hydrodynamic models，and hydraulic gate models. The twin-based scheduling system enables real-time monitoring and visualization of early warning information for water resource scheduling simulation scenarios in the Hexi Main Canal. It supports precise simulation of gate water regulation within the twin scenario and offers predictive capabilities for dispatching plan rehearsals，signifi cantly enhancing the scientifi c accuracy and effi ciency of water resource scheduling. The fi ndings provide robust technical support for refi ned management of the Hexi Main Canal and off er a replicable construction approach and implementation path for building digital twin platforms in other irrigation districts.
