Core Viewpoint - The article highlights the significant role of the Miyun Reservoir in flood control during recent heavy rainfall in North China, showcasing its historical record inflow and storage capacity, while preparing for potential future rainfall events [1][3][5]. Group 1: Flood Control and Reservoir Management - The Miyun Reservoir experienced its highest inflow since its establishment in 1959, with a peak flow of 6,550 cubic meters per second, surpassing the previous record of 3,670 cubic meters per second [1][3]. - From July 23 to July 29, the reservoir accumulated 810 million cubic meters of water, while releasing 180 million cubic meters, resulting in a storage level of 36.24 billion cubic meters, exceeding the flood limit level by 3.56 meters [3][5]. - The reservoir began controlled releases on July 27, managing a discharge rate of 500 cubic meters per second, which was later adjusted based on upstream water conditions [3][4]. Group 2: Impact on Downstream Areas - The maximum flow in the Chaobai River reached 1,120 cubic meters per second on July 28, marking the highest flow since the reservoir's construction [6]. - The Tianjin Water Authority implemented measures to manage flood risks, including the operation of key water control facilities and monitoring river conditions to ensure safety during the flood [7][8]. Group 3: Insurance and Risk Management - The article discusses the importance of disaster insurance, particularly vehicle and agricultural insurance, in mitigating losses from flooding, emphasizing the need for consumers to understand their coverage [9][10]. - The establishment of a comprehensive disaster insurance system is highlighted, with ongoing pilot programs in various provinces aimed at enhancing disaster risk management and insurance coverage [11].
