Core Viewpoint - The article highlights the implementation of a smart flood prevention system in Hangzhou, which utilizes a comprehensive digital platform to enhance urban flood management during the rainy season, significantly improving response times and efficiency in handling water accumulation issues [1][2]. Group 1: Smart Flood Prevention System - Hangzhou has established a "one network management" platform that integrates a "heaven-earth-human" system for flood prevention, described as a "digital immune system" for the city [1]. - The platform includes 923 intelligent rain gauge stations capable of detecting rainfall changes as small as 0.1 millimeters, and it connects to 231 weather forecast data grids for predictive analytics [1]. - The system can forecast rainfall trends up to three hours in advance using AI algorithms, allowing for timely emergency responses [1]. Group 2: Efficient Response Mechanism - Each water accumulation point has a tailored response plan, detailing specific equipment and personnel needed for effective management [2]. - Between June 7 and June 10, the system detected minor water accumulation at six locations, with depths controlled to within 2 centimeters, demonstrating proactive management [2]. - The platform's "flood prevention brain" integrates 18 types of data, enabling real-time monitoring and rapid dispatch of response teams, which significantly enhances the efficiency of flood management operations [2].
