Predicting Floods 30 Minutes in Advance
...Real-Time Alerts Sent via AlimTalk
Gwangjin District in Seoul announced on July 2 that it has begun pilot operation of an "Inundation Safety Management System" to prevent flooding damage to semi-basement homes caused by heavy summer rainfall.
The district developed this system after being selected for Seoul City's "Testbed Seoul Demonstration Support Project" last year. The system is designed to predict flooding in advance by integrating artificial intelligence (AI) and Internet of Things (IoT) technologies, and to minimize loss of life and property among disaster-vulnerable groups.
The demonstration site is located near the Junggok Rainwater Pumping Station along Gingorang-ro in Junggok 1-dong, a low-lying area. IoT water level sensors have been installed in 30 manholes throughout the area, following the flow of the sewer system.
Real-time data collected by the sensors is analyzed by AI, and the analysis results are immediately accessible through the district office's monitoring system. The system can set prediction values at 10-minute, 20-minute, and 30-minute intervals, enabling proactive monitoring and response.
In addition, a two-way notification service is operated using KakaoTalk AlimTalk. Depending on the risk level?safe, caution, alert, or severe?residents receive real-time information, helping to secure the golden time for evacuation.
The "Inundation Safety Management System" operates and is managed based on automated diagnosis and remote inspection. During normal conditions, it analyzes water level data to detect abnormalities in the sewer system.
The district will focus on operating the system during the rainy season until August this year. It aims to achieve a prediction accuracy rate of 95 percent, will rigorously verify the results, and, if proven effective, plans to expand the system to other areas.
Kim Kyungho, head of Gwangjin District Office, stated, "We are operating this inundation prediction system in line with an era where data-driven preemptive response saves lives," adding, "We will thoroughly prepare to protect residents from localized heavy rainfall."
