Studying Urban Delta Adaptation: The Comparative Analysis for the Urban Morphology to Mitigating Flooding Risk

Urban deltas, characterized by intense activities and disproportionately significant populations, are particularly susceptible to flooding risks. To ensure sustainable development in the face of climate change and increased flooding risks, it is crucial to adopt a resilient approach towards urban morphology. Theorizing urban morphology to flood capacity in conjunction with urban form allows for a more feasible estimation of floods on a large scale. It provides a more holistic understanding of the complex relationships between floods and cities. As such, this study aimed to analyze the frameworks of urban morphology in delta regions and their relationship to flooding risks to inform future urban planning and development efforts. Through the comparative analysis, we studied ten cases to investigate the similarities and differences in their approaches and frameworks, examining their perspectives to theorize the flood risk. The result showed that while the cases shared some commonalities in optimizing urban form to reduce flood risks, they also displayed variations in their frameworks to respond to the different scales. The study emphasized the significance of diverse classifications of urban form and their frameworks in effectively managing flooding risk, thereby supporting the sustainable development of urban deltas. These findings provide valuable guidance for future urban planning and related research.
