近日，黄河流域遭遇连续强降水过程，引发中上游洪水。为确保黄河中下游防洪安全，小浪底水利枢纽自8月9日起，逐步提高下泄流量，至8月12日达到最大3000立方米每秒，并开启全部3条排沙洞，累计排沙量近4000万吨。这是自8月2日关闭排沙洞后，小浪底水利枢纽第二次启动汛期调水调沙运用。
小浪底水利枢纽作为黄河下游的关键水利工程，承担着防洪、减淤的重要任务。面对此次洪水，小浪底枢纽密切监测雨水沙情变化，依托数字孪生平台科学制定防汛调度和调水调沙方案，精准调度水量，确保了防洪减淤效益的充分发挥。
此次调水调沙，不仅有效缓解了黄河中上游的洪水压力，还减轻了黄河下游的防洪负担，对保障沿岸人民群众生命财产安全具有重要意义。同时，这也是小浪底水利枢纽在应对复杂水情方面的又一次成功实践，展示了其在黄河治理中的“大国重器”作用。
小浪底水利枢纽的科学调度和高效运作，得到了水利部门和专家的高度评价。他们认为，此次调水调沙的成功，不仅体现了我国在水资源管理和水利工程运用方面的先进技术，也为其他类似工程应对洪水提供了宝贵的经验。
未来，小浪底水利枢纽将继续发挥其重要作用，为黄河流域的防洪安全和社会经济发展做出更大的贡献。同时，水利部门也将继续加强水情监测，及时应对可能出现的各种水情变化，确保黄河流域的长期稳定和可持续发展。

Title: Xiaolangdi Hydropower Station Initiates Water Diversion and Sedimentation Operations to Address Floods in the Middle and Upper Reaches of the Yellow River
Recent heavy rainfall in the Yellow River Basin has led to floods in the middle and upper reaches, necessitating measures to ensure flood safety in the lower reaches. Since August 9, the Xiaolangdi Hydropower Station has gradually increased its discharge flow, reaching its maximum of 3,000 cubic meters per second by August 12. All three sand discharge tunnels have been opened, resulting in a cumulative discharge of approximately 4000万吨 sand. This is the second time the Xiaolangdi Hydropower Station has activated flood season water diversion and sedimentation operations since closing the sand discharge tunnels on August 2.
As a key water conservancy project in the lower reaches of the Yellow River, Xiaolangdi Hydropower Station plays a crucial role in flood prevention and sediment reduction. In response to the recent floods, the hydropower station closely monitors changes in rainfall, water, and sediment levels, and uses a digital twin platform to scientifically formulate flood control and water diversion and sedimentation plans. Accurate water management ensures the full realization of flood prevention and sediment reduction benefits.
The water diversion and sedimentation operations have not only effectively alleviated the flood pressure in the middle and upper reaches of the Yellow River but also lightened the flood defense burden in the lower reaches, which is of great significance for the safety of lives and property of the people along the river. This is another successful practice of the Xiaolangdi Hydropower Station in dealing with complex water conditions, showcasing its role as a “national treasure” in Yellow River governance.
The scientific scheduling and efficient operation of the Xiaolangdi Hydropower Station have been highly praised by water conservancy departments and experts. They believe that the success of this water diversion and sedimentation operation not only reflects advanced technologies in water resource management and hydropower engineering operation in China but also provides valuable experience for other similar projects in dealing with floods.
In the future, the Xiaolangdi Hydropower Station will continue to play a vital role in ensuring flood safety in the Yellow River Basin and making greater contributions to social and economic development. At the same time, the water conservancy departments will continue to strengthen water condition monitoring and promptly respond to possible changes in various water conditions to ensure the long-term stability and sustainable development of the Yellow River Basin.
