Proceedings of The HKIE Geotechnical Division 42nd Annual Seminar: A New Era of Metropolis and Infrastructure Developments in Hong Kong, Challenges and Opportunities to Geotechnical Engineering.
The conventional practice of construction site monitoring in Hong Kong relies heavily on in-person site inspection, which is inherently subject to limitations in human resources, health, safety and time. Additionally, given that the advent and applic

Proceedings of The HKIE Geotechnical Division 41st Annual Seminar: Adapt to Challenges, Create to Thrive.
Establishing landslide models plays a critical role in Natural Terrain Hazard Studies (NTHS). Conventional approaches adopted by NTHS practitioners may be subject to temporal and spatial limitations. In particular, landslide volume estimations are pr
