今年入秋以来,汉江流域迎来密集"大小考":汉江上游相继形成7次编号洪水,为1961年有实测资料以来"最 密集秋汛"。在完善的防汛体系支撑下,汉江干流所有监测站点水位均未超警戒。同时,丹江口水库水位已 成功蓄至170米正常蓄水位,在闯过洪水考验的同时,圆满完成了蓄水任务。 汉江秋汛防御与汛末蓄水取得"双胜利"的背后,离不开水利部门的精准预测与科学统筹。连日来,水利部 长江水利委员会(以下简称"长江委")科学调度水库群拦洪、削峰、错峰,防蓄兼顾,精准控制丹江口水库 出库流量和梯级水库蓄水节奏,全力守好汉江流域和南水北调中线工程水安全底线。 科学决策,迎战罕见秋汛 今年1-8月,汉江流域降雨、来水持续偏少,一度遭遇极端枯水;然而8月下旬后,强秋雨接踵而至,旱涝转 折。9月5日至10月18日,汉江上游接连迎来7次编号洪水,其中2-5号洪水集中在15天内发生,为有实测资料 以来"最密集秋汛"。 据水利部消息,今年汉江秋汛呈现四个显著特点,秋汛开始早、持续时间长;降雨过程频繁、雨量大;编号 洪水次数多、间隔时间短;洪水总量大。 面对严峻汛情,以丹江口水库为核心的汉江流域水库群联合调度,成为防洪的关键。 "丹江口水库在9月 ...

Core Viewpoint - The article discusses the advancements in flood prevention and management along the Yangtze River, highlighting the integration of cutting-edge technologies such as artificial intelligence, digital twins, and high-performance computing into traditional flood defense systems to enhance forecasting, warning, and inter-departmental collaboration [1][5][8]. Group 1: Technological Advancements - The Yangtze River Water Resources Commission has transitioned from experience-driven to data-intelligent practices in flood prevention, utilizing AI, digital twins, and high-performance computing [1][4]. - The "Thousand-Mile Eye" system provides comprehensive monitoring across the Yangtze River basin, covering an area of 1.8 million square kilometers and generating up to a million data points daily, with a reporting rate of 99.8% within 20 minutes [2][4]. - The "Strongest Brain" employs AI and big data analytics to create a multi-time scale quantitative precipitation forecasting system, achieving a short-term forecasting accuracy of over 90% for the middle and lower reaches of the Yangtze River [5][7]. Group 2: Integrated Monitoring Systems - The "Sky, Earth, Water, and Engineering" integrated monitoring system combines data from 86 radars, meteorological satellites, and approximately 50,000 hydrometeorological stations to facilitate proactive flood management [4][8]. - The system allows for real-time simulation of flood scenarios, enabling decision-makers to visualize potential risks and assess the impact of various flood management strategies [10][11]. Group 3: Decision-Making Support - The "Digital Twin Yangtze" system provides a visual representation of flood management strategies, allowing for real-time simulations and comparisons of different operational plans to identify the optimal approach [8][10]. - The integration of human expertise with machine calculations enhances the accuracy of flood predictions, with nearly 1,000 simulations conducted this year to support flood management efforts [7][10].
