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]

"这两公里沟道我负责，每天至少要跑一圈。"7月23日，雅安市汉源县安乐镇安乐村党支部书记马凤倡骑上摩 托车，顺着白岩河巡查隐患，"主要看看沟道有没有淤堵和其他隐患，桥梁涵洞尤其要看仔细。" 今年汛期开始后，马凤倡多了一个身份——村级沟长。和他一起上任的，还有其他5位村级沟长、8位乡 （镇）级沟长、1位县级沟长以及11位点长，他们共同守护着白岩河流域。 雅安市汉源县白岩河。记者 李志强 摄 防汛实招 以沟域（流域）为单元，实行沟长制分级管理机制，结合实际情况设立沟长，实现山洪沟、泥石流沟、山洪 泥石流沟全覆盖。 一线探访 记者了解到，这些沟道往往跨村、跨镇甚至跨县分布，防灾减灾工作涉及水利、自然资源等多个部门，可能 出现上下游、左右岸之间缺乏统筹，防灾减灾难以形成合力等情况。此外，此前省内外山洪泥石流灾害案例表 明，沟道常常出现沟顶上游暴雨、沟口下游天气晴朗的情况，导致灾害风险研判难度大。 针对这一痛点，四川在现有山洪泥石流沟群测群防体系基础上，以山洪泥石流沟域（流域）为单元，结合科 技赋能防灾减灾成果运用，开展沟长制试点。具体而言，就是以沟域（流域）为单元，实行沟长制分级管理机 制，结合行政区域设立沟长，"一 ...
