Technology Helps Urban Flood Prevention: Practice in Fuzhou Region

2025-07-11 16:06:53

On July 11th, there was heavy rainfall in the Fuzhou area, with Mawei District being the area with the highest precipitation in the urban area, with an hourly rainfall of up to 80.6 millimeters, resulting in severe water accumulation on some roads. In this emergency situation, water meters installed in low-lying areas played an important role in quickly measuring and reporting the depth of accumulated water, providing valuable data support for urban flood prevention.

There are two main types of water meters we use: buried road surface water meters and electronic water gauges. They all use built-in batteries for self powering and transmit data wirelessly, ensuring continuous operation in harsh weather conditions. These devices have undergone various inspections, repairs, and maintenance before the typhoon season, ensuring their good operation.

The buried road surface water meter uses induction technology to monitor the real-time water situation of the road surface by burying it below the ground, and the data is uploaded to the monitoring center in real time through wireless network. The electronic water gauge provides more intuitive data on the depth of accumulated water by directly measuring the water depth. The application of these technological means not only improves the accuracy of water accumulation monitoring, but also greatly shortens the time for emergency response.

This practice in the Fuzhou region demonstrates the important role of modern technology in urban flood prevention. By deploying and maintaining monitoring equipment in advance, city managers can respond more quickly to emergencies and reduce the impact of heavy rainfall on citizens' lives. This successful experience also provides useful reference for other cities, emphasizing the importance of technology in improving urban management and disaster response capabilities.

In the future, with the continuous advancement of technology, urban flood prevention systems will become more intelligent. By further integrating advanced technologies such as the Internet of Things, big data, and artificial intelligence, urban managers can achieve multi-faceted real-time monitoring and intelligent scheduling of rainfall, waterlogging, and drainage systems, providing citizens with a safer and more comfortable living environment. The successful practice in the Fuzhou region is a powerful example of this trend towards intelligent urban management.
