"我报考水利专业是因为一张白面饼。"张金良回忆，"小时候，一次烙了一天的饼，但母亲告诉我不能 吃，这是给灾区的。"水灾多发，让童年的他萌发了学水利的志向。 1985年，22岁的张金良从天津大学毕业。此后的14700多个日夜，张金良的人生轨迹始终与黄河重叠。 "服务治黄是我们存在的价值。"他的办公室堆满图纸资料，墙上挂着巨幅黄河流域图，红蓝标记密布。 最显眼处，是一张泛黄的照片——2002年，我国首次黄河调水调沙试验现场。 黄河西来决昆仑，咆哮万里触龙门。12月7日，大雪节气，一位头发花白、戴着黑色半边框眼镜的长者 穿梭在黄河在建项目施工现场，神情专注，时不时给出建议。 他就是荣获首批"河南楷模"称号的张金良，黄河勘测规划设计研究院有限公司首席科学家。四十余载春 秋，从青丝到白发，他把人生最美的年华，都献给了这条中华民族的母亲河；他攻克了一系列制约黄河 治理的世界级难题，以技术创新推动黄河治理技术实现多项从"0"到"1"的突破。 "黄河需要什么，我们就研究什么" 时任黄河防办主任的张金良在防汛指挥部连续值守七天七夜，和同事们吃住在办公室，眼睛里布满血 丝。"那是水利史上最大规模的人工原型试验。"回忆往事，张金良 ...

Core Viewpoint - The construction of the Dongzhuang Water Conservancy Hub is a significant development project aimed at enhancing flood control, sediment management, and regional water supply in Shaanxi Province, contributing to the ecological protection and sustainable development of the Yellow River basin [1][3][4]. Group 1: Flood Control and Sediment Management - The Dongzhuang Water Conservancy Hub will improve flood control standards from a 10-year to a 20-year frequency, reducing the impact of 100-year floods to 50-year floods in the Weihe River downstream [3]. - The project is expected to intercept 3.051 billion tons of sediment from the Jing River and 2.5 billion tons from the Yellow River, significantly alleviating the sediment burden on the downstream waterways [3]. Group 2: Water Supply and Irrigation - Upon completion, the hub will provide an annual water supply of 435 million cubic meters to urban and industrial areas, achieving a water supply guarantee rate of 95% [4]. - The irrigation guarantee rate for the Jinghui Canal irrigation area will increase from 30% to 50%, supporting regional agricultural development [4]. Group 3: Power Generation and Environmental Impact - The hub will feature four mixed-flow generating units with a total capacity of 110 megawatts, generating an average of 285 million kilowatt-hours annually, saving 90,000 tons of coal and reducing carbon dioxide emissions by approximately 250,000 tons [4]. - The project will create a 97-kilometer long water surface area, improving local microclimates and providing better habitats for fish and migratory birds [5]. Group 4: Technological Innovations and Milestones - The planning and construction of the Dongzhuang Water Conservancy Hub have involved overcoming significant technical challenges, leading to the development of advanced systems such as digital twin technology and visual monitoring platforms [6]. - The project is recognized for several world-first achievements, including being the first high arch dam built primarily for flood control and sediment reduction [6].
