ABSTRACT

Deltas are vulnerable to river and seawater flooding due to their low-lying topography and proximity to bodies of water. In the port city of Busan in Korea, the oceanic climate’s heavy rain increases the risks and concerns of subsequent rainwater flooding. The master plan of Eco-Delta City acknowledges these flood risks and includes a number of mitigation strategies. It adopts different types of structural and non-structural mechanisms, including a ground elevation level increase, which takes into account the 200-year flood plain, a wide riparian buffer zone, and low-impact development strategies. The plan’s Intelligent Flood Monitoring System uses innovative IoT (Internet of Things) and digital twin technologies to provide enhanced flood management.
