Abstract：As a key technology promoted by national and water conservancy departments,digital twin technology has been widely applied in water conservancy and hydropower projects as well as other industries.It also plays a significant role in the management and protection of rivers and lakes,particularly in the"Happy Rivers and Lakes"initiative strongly advocated by the Ministry of Water Resources.The construction of digital twin Happy Rivers and Lakes adheres to the principles of"demand-driven,application-oriented,digitally empowered,and system upgrade."Through the integration of digitization,networking,and intelligent technology systems,a closed-loop technical path of"3D modeling-intelligent simulation-decision optimization"is constructed.Focus is placed on deploying full-domain perception networks and multi-source data fusion to create a smart river and lake management platform with functions of forecasting,warning,rehearsal,and planning(Four-Pre).This simultaneously promotes the digital transformation of the River Chief System,achieving real-time situational awareness,scientific decision analysis,and precise scheduling and control of basin governance.Consequently,a digital twin system for Happy Rivers and Lakes has emerged,aiming to enhance river and lake management capabilities through online digital twin platforms and offline management system innovations,thereby assisting in the construction of Happy Rivers and Lakes.
