Description
Global climate change has significantly increased the frequency of extreme weather events, with floods becoming an increasingly severe and unpredictable threat to urban areas. Consequently, flood control has emerged as a critical strategy to ensure public safety, particularly in transitional zones between urban areas and water bodies, such as waterfronts. In response, the city of Chongqing, China, has proposed raising the flood protection standards for its downtown waterfront areas. However, this proposal presents a conflict between meeting sustainable urban development needs and ensuring flood safety, as much of the surrounding land may fall within the newly designated floodplain, severely restricting its potential for development and regeneration. This research seeks to resolve this issue by presenting three key elements: (1) a flood resilience model based on resilience thinking and complex adaptive systems theory; (2) a risk distribution matrix developed from flood risk analysis under various scenarios and spatial vulnerability assessments; and (3) systematic solutions that integrate spatial planning and design, flood protection engineering, and risk management to determine the most suitable development intensity for different risk zones while ensuring flood safety and minimizing land resource consumption.
