针对复杂严峻的雨情和水情，广西水利部门滚动推演会商，科学精准调度郁江流域的百色、左江、老口、西津、那板等15座水库水电站，通过提前预泄 降低江河底水、坦化洪峰加快洪水行进和拦洪错峰，实施精细的水库群联合调度。10月6日2时，利用明江上游那板水库全力拦蓄洪水1.23亿立方米，降低宁 明县城洪峰水位2米以上，减轻明江下游防洪压力；科学研判，及时与珠江委会商研判，10月7日11时起，百色水利枢纽逐步将4500立方米每秒的入库流量减 少为1810立方米每秒出库，削减出库60％，百色市城区于7日19时退至警戒水位以下；7日21时起，百色水利枢纽按不大于1400立方米每秒控制，减少出库流 量400立方米每秒；8日10时起，百色水利枢纽出库流量按900立方米每秒控制。在洪水汇流前，预泄腾库尽力挖掘防洪库容，洪水发生时精细调度充分发挥 防洪减灾作用，以加快下游右江、郁江及支流退水，与区间洪水错峰，减轻下游防洪压力。经洪水演进分析，可减少南宁洪峰流量约1800立方米每秒，降低 洪峰水位1.5米以上，有力保障南宁市等防洪安全，最大限度避免沿线低洼地区受淹。（周映 周也茹） 自治区水文中心预测，未来12小时，右江、左江以退水为主， ...

Group 1 - The Guangdong Provincial Development and Reform Commission approved the feasibility study report for the Huangmaoxia Reservoir project, marking the commencement of substantial construction for this major water conservancy project [1] - The Huangmaoxia Reservoir is a key water conservancy project promoted by the Guangdong Provincial Party Committee and Provincial Government, aimed at enhancing the flood control capacity of the Beijiang River basin and improving navigation and irrigation conditions [1] - The project is expected to alleviate flood pressure in cities like Guangzhou and Foshan, thereby enhancing the flood resilience of the Guangdong-Hong Kong-Macao Greater Bay Area [1] Group 2 - The Huangmaoxia Reservoir will serve multiple functions including flood control, energy supply, navigation improvement, and agricultural efficiency, aligning with regional economic development, ecological protection, and public welfare needs [2] - The project aims to provide reliable water security for urban clusters in the Guangdong-Hong Kong-Macao Greater Bay Area while addressing diverse public demands for disaster prevention, sustainable development, and legal rights protection [2] - The engineering initiative will also focus on ecological protection and rural development, enhancing the living environment and promoting green and beautiful Guangdong ecological construction [2]

Core Viewpoint - The article emphasizes the urgent need to enhance flood prevention and control measures in China due to the increasing frequency and intensity of extreme rainfall events driven by global climate change [1][2]. Group 1: Flood Prevention Strategies - The establishment of a modern rainwater monitoring and forecasting system is crucial, transitioning from monitoring "ground rain" to "cloud rain" and improving flood prediction accuracy and lead time [1]. - The first line of defense focuses on monitoring "cloud rain," advocating for the development of advanced rainfall radar systems and short-term precipitation forecasting models to enhance flood prediction capabilities [1]. - The second line of defense aims to improve "ground rain" monitoring by increasing the density of rain gauge stations in flood-prone areas and utilizing high-resolution geographical data for better flood forecasting [2]. Group 2: Flood Evolution Monitoring - The third line of defense involves monitoring the evolution of floods, recommending the optimization of hydrological station networks and modernization of measurement techniques to ensure reliable data for flood modeling [2]. - The article suggests implementing a modernized flood control engineering system, including the reinforcement of dangerous reservoirs and the construction of smart dams to enhance digital and intelligent management of water resources [2]. Group 3: Infrastructure and Management Enhancements - There is a call for improving the construction standards of critical levees and enhancing safety monitoring systems, alongside the management of flood retention areas through digital twin technology [2].

Group 1 - The mayor emphasizes the importance of implementing flood prevention measures and ensuring the safety of citizens during flood seasons [1] - The city is focusing on river channel management to enhance urban flood control capabilities and improve public safety and satisfaction [1] - The Yangtze River embankment is highlighted as a critical defense line, with plans for comprehensive safety inspections and long-term construction initiatives [1] Group 2 - Sufficient emergency flood prevention materials are deemed essential for effective disaster response, with a call for diversified supply channels [2] - The mayor stresses the need for enhanced emergency preparedness, including the establishment of robust rescue teams and modern monitoring systems [2] - Coordination among various departments is crucial for effective flood management, emphasizing a collaborative approach to disaster response [2]
