Core Viewpoint - Sichuan province successfully managed to avoid casualties during the flood season, which ended on September 30, 2023, despite facing nine regional heavy rain events and activating emergency responses multiple times [1] Group 1: Technological Advancements in Flood Control - Sichuan is enhancing its flood control capabilities through the deployment of 73 rainfall monitoring radars across the province, with the first 38 already operational by July 31, 2023 [2] - The rainfall radars provide real-time high-resolution rainfall data and can forecast rainfall 1 to 3 hours in advance, addressing the monitoring gaps in mountainous areas [2] - The introduction of the first batch of drone-deployable rain gauges, "Rain God-1," in August 2023, allows for monitoring in remote areas even under adverse conditions [3] Group 2: Innovative Mechanisms for Disaster Reduction - The integration of the Dujiangyan-Piziping reservoir management system allowed for proactive flood control by lowering reservoir water levels in anticipation of heavy rainfall, effectively reducing downstream flood levels by 2 to 3 meters [5] - The establishment of temporary evacuation shelters, termed "safety houses," has provided refuge for over 29,000 individuals threatened by mountain floods and geological disasters [5] - New mechanisms such as basin joint prevention and control, and the "30123" emergency response system have been implemented to enhance flood disaster reduction efforts [6]

Core Viewpoint - The article discusses the implementation of a "Gongzhang" (valley manager) system in Sichuan province to enhance flood disaster prevention and management, particularly focusing on mountain flood and debris flow hazards during the rainy season [5][7]. Group 1: Implementation of the Gongzhang System - Sichuan has initiated a pilot program for the Gongzhang system in areas such as Ya'an, Ganzi, Aba, and Liangshan to improve disaster prevention capabilities [5][7]. - The Gongzhang system involves a hierarchical management mechanism based on river basins, with designated managers responsible for each section, ensuring comprehensive coverage and coordination among various administrative levels [6][7]. - The system aims to address challenges in disaster management, such as the lack of coordination between upstream and downstream areas, by establishing clear responsibilities and communication channels [6][7]. Group 2: Responsibilities and Structure - The Gongzhang system includes a four-tier responsibility framework involving county, township, village, and point managers, ensuring that every section of the river and its tributaries is monitored and managed effectively [7][9]. - Specific responsibilities for each level of management have been outlined, including daily monitoring, emergency response, and communication of hazards to ensure a closed-loop management system [9][10]. - Over 3,600 debris flow channels have been selected for the Gongzhang system, with more than 3,400 managers and 8,900 point managers appointed across the province [9][10]. Group 3: Technological Integration - The implementation of the Gongzhang system will leverage technology such as flood forecasting systems, 3D modeling, and emergency communication tools to enhance disaster response capabilities [10]. - Continuous evaluation and improvement of the Gongzhang system will be conducted to ensure effective integration with existing disaster management frameworks [10].
