Drainage Services Department Engineers Present Smart Flood Resilience Solution at "Science in the Public Service" Lecture
18 October 2025
Engineers from the Drainage Services Department (DSD), Mr Jeff NG Man-po and Miss Gloria WONG Chi-kau, introduced a novel smart flood resilience solution named "Artificial Intelligence (AI) Flood Monitoring System" at the "Science in the Public Service" lecture held at the Hong Kong Science Museum on 18 October 2025.
To address the growing challenges of extreme weather, this system developed by the department and the University of Science and Technology innovatively employs generative artificial intelligence, specifically visual language models, to perform integrated analysis of real-time data from surveillance footage, sensors and weather forecasts.
During the lecture, the engineers provided a detailed explanation of the technical principles and application potential of generative AI and visual language models. By comprehensively analysing diverse data streams to estimate flood depth, conduct dynamic risk assessment and issue real-time warnings, the system represents a strategic transformation for Hong Kong - shifting its flood management approach from a "reactive" stance to a "proactive" paradigm of early warning and pre-emptive control. This advancement significantly enhances the city's overall flood resilience and operational response effectiveness.
