Core Viewpoint - The article discusses the new measures taken by relevant departments in flood control engineering, emphasizing the need for a comprehensive approach to enhance flood prevention and disaster reduction capabilities in river basins [1][2]. Group 1: Flood Control Measures - The Central Committee and the State Council have issued opinions on advancing river protection and governance, aiming to establish a new pattern for flood prevention and disaster reduction in river basins [1]. - The flood control engineering system consists of reservoirs, river channels, levees, and flood retention areas, with a focus on scientific planning and systematic governance to enhance proactive flood management capabilities [1]. Group 2: Infrastructure Development - The water resources department is accelerating the construction of key projects and addressing shortcomings, including a three-year action plan for the reinforcement of dangerous reservoirs and the establishment of national flood retention areas [1][2]. - The article highlights the completion of boundary work for 14 national flood retention areas in the Haihe River basin, addressing issues such as inadequate levee standards and insufficient flood control facilities [2]. Group 3: Technological Integration - The integration of digital technologies, such as digital twin technology, is being utilized to improve flood response times, significantly reducing simulation time for flood progression from 40 minutes to under 5 minutes [2]. - The Ministry of Water Resources plans to accelerate the construction of digital twin river basins and water conservancy projects to enhance the scientific and forward-looking nature of flood prevention decision-making [3].

Group 1 - The core objective of the research is to enhance water security in the Songliao River Basin, focusing on high-quality development and addressing key issues in water resource management [1][4] - The research emphasizes the need for a comprehensive water network layout to ensure water supply security, considering the uneven distribution of water resources in the region [2] - The study aims to strengthen flood control measures by identifying and addressing weaknesses in flood management systems, including reservoir operations and flood channel construction [3] Group 2 - The initiative includes systematic governance to maintain the ecological health of rivers and lakes, with specific goals for the ecological restoration of the Xiliao and Hohlin Rivers [4] - The planning process involves extensive field research and stakeholder engagement to gather insights and recommendations for effective water management strategies [1][4] - The Songliao Water Resources Committee is committed to developing actionable plans for flood safety, water supply security, resource conservation, and ecological restoration [4]

Core Viewpoint - The article discusses the critical flood prevention period in China, highlighting the challenges posed by extreme weather events and the measures taken by the Ministry of Water Resources to ensure safety and effective disaster response during this time [1][2][4]. Group 1: Flood Prevention Measures - The flood prevention period, known as "Seven Down, Eight Up," is characterized by complex and severe flood conditions, with early onset of flooding and extreme droughts in various regions [1][2]. - The Ministry of Water Resources has established a comprehensive flood disaster prevention system consisting of three main components: rainwater monitoring and forecasting, flood disaster defense work, and flood control engineering systems [1][4]. Group 2: Monitoring and Forecasting Systems - A total of 101 rain monitoring radars have been installed across 24 provinces, significantly enhancing the ability to monitor and forecast rainfall [3]. - The rainwater monitoring and forecasting system has been successfully applied during recent extreme weather events, providing timely warnings that facilitated the evacuation of over 100,000 people during severe flooding in Guizhou Province [5][3]. Group 3: Responsibility and Coordination - The Ministry of Water Resources has published a list of 2,792 flood prevention responsibility holders to ensure accountability and effective disaster management [4]. - 23 provinces have established flood disaster defense centers to enhance decision-making support and coordination during flood events [5]. Group 4: Engineering and Infrastructure - As of the end of 2024, there are 318,000 kilometers of levees in China, with 77,000 kilometers classified as important levees [6]. - The Ministry has completed the spatial coordinate mapping of 291,000 kilometers of levees, which will aid in real-time monitoring and decision-making for flood prevention [6]. Group 5: Flood Control Effectiveness - During the response to Typhoon "Butterfly," major reservoirs in the Pearl River, Yangtze River, and Taihu Lake basins were utilized to store 6.67 billion cubic meters of floodwater, demonstrating the effectiveness of the flood control engineering system [7].
