Urban form and natural hazards: Exploring the dual aspect concept of urban forms on flood damage

Abstract

The purpose of the paper is to explore the dual aspect concept of the impact of urban forms on flood damage. Theoretically, urban form has the dual aspect concept of increasing or decreasing flood damage. Recent issues such as climate change and pandemics are increasing the need to re-discuss the relationship between urban forms and natural hazards. By revisiting the dual aspect concepts of urban forms such as aggregation and dispersion, we can effectively respond to specific urban problems that present complex issues at the city level. Accordingly, this paper once again considers what is a more resilient and ideal urban form for natural hazards by exploring dual aspect concepts of urban form for flood damage spatially and quantitatively from a macroscopic point of view.
