A Sensor-Based Smart Urban Flood Warning and Management System

In recent years, the rapid global climate change has resulted in frequent urban flooding disasters. The phenomenon of blocked drain covers in urban areas directly affects the passage of vehicles and pedestrians, causing inconvenience to citizens' travel. In severe cases, it can even submerge vehicles, leading to casualties and posing a serious threat to public safety and property. To address this issue, we propose a smart urban flood warning and management system. The system installs terminal devices on rainwater grates along the roadsides. When the water level on the road reaches a certain depth, pressure sensors are used to acquire the water level information, which is then uploaded to the server. The system provides realtime and accurate feedback on urban flooding conditions, demonstrating broad prospects for the prediction and control of urban flooding disasters.
