Investigation of Transport Logistics Disruptions from Urban Floods: A Case Study of the Chinese Coastal Megacity—Guangzhou, China

Chinese coastal megacities face an increasing challenge on urban floods in light of climate change and rapid urbanisation. Severe urban floods worsen damages of public infrastructures, such as roads and railway networks, because the land drainage system is currently insufficient to cope with intensive rainstorms. This condition is particularly severe in most Chinese megacities. As a result, that disrupted the transport system and logistics, which associated the interruption of economic and business opportunities. This paper took Guangzhou, the leading commercial and manufacturing hub in the Greater Bay Area region, as a case study. Unfortunately, the city is currently exposed to a high level of urban flood risk. By analysing the historical data, this research summarised the annual rainfall pattern in Guangzhou, and presented the potential impacts of the urban flood on logistics disruption based on the layout of road surface water flooding. Our findings in this research aim to provide recommendations on logistics disruption and transportation plan for road users in future flood events. Moreover, the results are insightful in tackling future urban floods to improve current policies on achieving resilient city planning on logistics.
