Core Viewpoint - The article highlights the comprehensive implementation of a digital twin system in water management in Zhejiang, which enhances the efficiency and precision of water resource management through real-time data monitoring and analysis [1][2][5]. Group 1: Digital Twin System Implementation - The digital twin system creates a virtual representation of physical water management entities, enabling real-time monitoring, analysis, and optimization [2]. - Zhejiang has established a "1+3+N" planning framework for digital twin water management, which includes a comprehensive sensing network and a provincial digital twin platform [2]. - As of now, 69 digital twin projects have been successfully implemented, marking a significant transition from initial breakthroughs to broader enhancements [2]. Group 2: Enhanced Monitoring and Response - The average density of rainfall stations in Zhejiang has reached one station per 6.2 square kilometers, ensuring comprehensive coverage for timely flood warnings [3][4]. - The efficiency of flood warnings has improved by 50%, with the response time reduced from 30 minutes to 15 minutes [3]. - The integration of various resources, including satellite, radar, and ground monitoring, has created a high-precision sensing network for effective water management [4]. Group 3: Water Resource Management Success - During a drought in August 2024, the digital twin water network model enabled the effective management of water resources, resulting in the delivery of 7.54 million cubic meters of water to alleviate drought conditions [5]. - Ningbo has established over 14,000 monitoring points to create a smart water network that optimizes water supply and management across various water sources [6]. - The digital twin system in Ningbo has maintained a water supply guarantee rate of 99.8% during drought conditions by optimizing reservoir and water plant operations [6]. Group 4: Future Directions - The ongoing development of the digital twin technology aims to enhance the resilience, intelligence, and public benefit of modern water networks, with plans to share successful practices nationwide [6].

"通过布设覆盖水位、水量等指标的全要素感知体系，实现了康门水库大坝安全在线监测与动态风险预 警。"工作人员介绍道。这一实践正是杭州全力打造水利物联感知网络的生动缩影。康门水库的全要素 感知建设实践，正是杭州全力打造水利物联感知网络的生动缩影。 在水利部试点项目青山水库智能大坝建设中，技术突破更亮眼。通过8颗水利一号组网卫星，测量周期 由传统的12天提升到2天，雷达成像技术可以不受云层、光线影响，数据获取"全天无休"，实现亚毫米 级变形监测和分米级水域监管。 如果说数字孪生是水利工程的"智慧大脑"，感知网络便是连接物理世界与数字空间的"神经末梢"。杭州 充分运用新一代信息技术，建立"天基、空基""落地雨""洪水演进"监测预报防线，夯实"天空地水工"监 测感知一张网，为水利工程高保真建设运行提供有力算据保障。 四预一体化 指导全方位防洪调度 商报讯（记者 蔡杭吉 通讯员 冯晴颖 ）钱塘江畔，数字浪潮正绘就杭州水脉治理新图景。昨天，水利部 在杭州召开数字孪生水利建设现场会，现场考察萧山枢纽、之江水文站、西江塘等数字孪生水利建设成 果。会场外，杭州康门水库全要素构建现代化水库管理矩阵数据监测体系、西险大塘数字孪生系统 ...
