Demand Context

Empowering smart urban flood control through real‑time monitoring and early warning.

With the acceleration of urbanization, the problem of urban flooding caused by extreme weather has become increasingly severe, adversely affecting people's lives and the economic development of cities. To more effectively address urban flood management and monitoring, it is essential to establish and improve monitoring and early warning mechanisms for flood-prone areas, thereby comprehensively enhancing disaster monitoring and early warning capabilities. Therefore, developing an efficient and accurate urban flood monitoring and early warning system to predict flood risks in advance and respond promptly has become a crucial measure for ensuring the safe operation of cities. This system provides scientific support for urban management and emergency response, thereby minimizing the impact of disasters.

Key Challenges

Scattered Hydrological Data

Rainfall, water level and flow data from different low‑lying areas are siloed, hindering holistic urban flood assessment.

Delayed Warning Dissemination

Without real‑time thresholds and automated alerts, citizens and responders are notified too late, increasing risks.

High Emergency Costs

Reactive emergency response and lack of coordinated dispatch increase resource waste and damage severity.

Weak Decision Support

Historical data is not fully utilized to predict waterlogging patterns or optimize drainage infrastructure.

Solution Overview

IoT‑enabled urban flooding monitoring integrating real‑time data, GIS mapping, and intelligent emergency linkage.

Intelligent water level sensors, rain gauges, and video surveillance equipment are deployed in critical urban areas (such as low-lying zones, key drainage system nodes, and major road intersections). These devices collect real-time data on rainfall, water level changes, and flow velocity. Data is gathered via WideIOT hydrological gateways and transmitted remotely through 5G/4G or fiber-optic networks to the Urban Flood Monitoring and Early Warning Center, enabling real-time monitoring. When water levels exceed thresholds or equipment malfunctions, the system automatically triggers alarms and sends warning notifications to responsible personnel via SMS and other channels. This alerts relevant departments to take immediate action to resolve flooding issues. Simultaneously, public guidance is disseminated through radio, television, and LED displays to inform citizens about travel routes, preventing people and vehicles from entering deep water areas and avoiding significant losses.

Programme Benefits

Comprehensive urban flood control through intelligent monitoring and coordinated response.

Real-time Monitoring

Real-time monitor parameters such as water level, liquid level height, rainfall, and flow velocity. The monitoring frequency can be set for 24/7 uninterrupted operation. Urban waterlogging and water accumulation status as well as video images can be monitored in real time through mobile terminals, PC terminals, and data dashboards.

Map Positioning

Supports GIS geographic location display to centrally monitor real-time water level data and water accumulation conditions at various waterlogging points in the city. On-site location information, basic information, and real-time status can be displayed through manual switching and automatic query, facilitating overall management and layout.

Flood Control Early Warning

Supports flood control early warnings for heavy rains, water accumulation, etc. The system automatically alarms when water level is too high or equipment is abnormal. Warning information can be pushed to responsible persons via SMS, email, WeChat, etc., enabling timely measures to solve problems.

Intelligent Linkage

Preset corresponding waterlogging and flood control parameters to predict the arrival of waterlogging in advance. Link with LEDs to release real-time information to prevent personnel and vehicles from entering deep-water sections. Meanwhile, link and control on-site drainage equipment for timely drainage to avoid and delay urban waterlogging.

Emergency Response

Establish a linkage mechanism with urban emergency management, transportation, fire protection and other departments. Quickly formulate emergency plans to guide emergency teams in rapid response, conduct timely drainage operations, traffic diversion and personnel evacuation, reduce the impact of water accumulation, and improve emergency response capabilities.

Data Analysis

Establish an analysis model based on historical data and real-time monitoring data to mine valuable data that is more conducive to improving the level and efficiency of drainage and flood control management, providing a scientific decision-making basis for the government and relevant departments.
