Water Grid Construction of Xiangsi River Based on Balanced and Twin Perspectives
Global climate change,coupled with human activities,has led to significant alterations in rainfall patterns,water avail-ability,infrastructure conditions,and societal contexts,complicating watershed management.Consequently,flood control and drought resistance face new challenges.This paper presented a comprehensive analysis of the Xiangsi River basin's river system,hydrological characteristics,and disaster features.Based on this analysis,the paper preliminarily explored the construction ap-proach for the water network engineering system in the Xiangsi River basin from the perspectives of balance and twinning.It is rec-ommended that the planning of the water network engineering within the Xiangsi River basin should balance the general and the specific as well as supply and demand,maximizing benefits and minimizing drawbacks.An integrated strategy should be adopted to address flood control and drainage issues,create an extensive urban water system,and facilitate the optimized distribution of water resources.The construction of a digital twin water network enables the synchronous simulation and virtual-physical interaction of the Xiangsi River's physical and digital basins.This facilitates the establishment of a critical process simulation and rehearsal plat-form for flood and drought events,coordinats the relationship between flood conveyance and storage,and harmonizes flood interac-tions within the Xiangsi River basin and its bi-directional flow dynamics with the Liangfeng River and Luoqing River.The research findings offer insights for enhancing the flood control and disaster reduction capabilities of digital water networks,improving the landscape value of urban rivers,and balancing water resource allocation in river basins.
