Core Viewpoint - The article emphasizes the importance of flood prevention and water storage management in the Yangtze River basin during the autumn flood season, highlighting the need for coordinated efforts among relevant departments to ensure safety and efficiency in operations [1][2]. Group 1: Flood Prevention Measures - The Yangtze River Flood Control Headquarters and the Yangtze River Water Resources Commission are actively monitoring rainfall changes and have scheduled specific flood defense and post-flood water storage tasks [1]. - A significant rainfall event is forecasted from October 17 to 18, with moderate to heavy rain expected across the Yangtze River basin, followed by light rain from October 19 to 26 [1]. Group 2: Responsibilities and Coordination - There is a call for enhanced accountability in flood defense, with daily assessments and a focus on optimizing work deployment to improve the effectiveness and timeliness of flood prevention measures [1]. - The need for strengthened monitoring, forecasting, and early warning systems is highlighted, particularly in response to heavy rainfall, to support decision-making and timely alerts [1]. Group 3: Water Resource Management - The article stresses the importance of scientifically managing reservoir operations, balancing flood safety with water storage needs, and optimizing the dispatch plans for key reservoirs like the Three Gorges and Danjiangkou [1]. - There is a directive for local areas to enhance inspections and defenses of riverbanks and to manage risks associated with small rivers and reservoirs, particularly those that are vulnerable or under construction [1]. Group 4: Safety and Quality Assurance - Ensuring the safety of the Danjiangkou Reservoir and its water quality is a priority, with ongoing monitoring and analysis of flood data to enhance engineering and water quality safety capabilities [2]. - The article also mentions the importance of public communication and media engagement to promote flood defense measures and operational effectiveness, fostering a supportive public opinion environment [2].

Core Insights - The Danjiangkou Reservoir has reached its normal water level of 170 meters for the third time since its dam height was increased, marking a significant achievement in flood prevention and water storage for the Han River basin [1][2] Group 1: Rainfall and Flood Characteristics - The Han River basin experienced extreme drought conditions from January to August, followed by an unusually strong autumn rain starting from late August, which is characterized by four notable features [1] - The autumn flood began early and has lasted longer than usual, starting on August 25, which is 8 days earlier than the average, and has continued for 55 days as of October 18, exceeding the average duration by 16 days [1] - There were 11 significant rainfall events during the autumn flood period, with the upper reaches of the Han River receiving a total precipitation of 573 millimeters, which is 2.8 times the average for the same period, marking the highest since records began in 1961 [1] - The frequency of numbered floods was high, with seven occurrences between September 5 and October 18, making it the most concentrated autumn flood period on record [1] - The total inflow to the Danjiangkou Reservoir during the autumn flood was approximately 29.7 billion cubic meters, which is about 2.7 times the average for the same period and the second highest since the reservoir was built in 1969 [1] Group 2: Water Management and Safety Monitoring - The Yangtze River Water Resources Commission is effectively managing the water resources by coordinating the Danjiangkou Reservoir and other control reservoirs in the Han River basin to achieve flood control and water storage goals [2] - Current safety monitoring data indicates that the dam's operational status is normal, water quality is stable and meets standards, and the safety of the reservoir banks is under control [2] - The Ministry of Water Resources and the Yangtze River Commission will continue to monitor rainfall in the Han River basin closely and enhance safety monitoring of the reservoir and its surroundings [2]
