Development and Urbanization
The article examines how the morphology and materiality of a territory could contribute to enhancing a certain level of security of the inhabitants facing the flood risk.
The notion of flood risk, both natural and anthropologic, has been studied and described by territory-related science subjects over the last fifteen years. These works elaborated the concepts of “risk-territory” and “resilience” to have a refined understanding of the relationship between spatial dynamics and flood risk. However there has only been few researches tangibly investigating the relationship between urban form and flood risk, whereas research on this topic could provide a sophisticated understanding on the question. Moreover, flood risk management is a complex task that involves a wide range of multidisciplinary individuals and institutions between whom a common language is partially lacking.
One of the challenges of this article is to assess if urban spatial configuration is designed to cope with flood risk throughout the process of urbanization. Based on systemic approach and the concept of resilience, our research problem is how to develop a qualitative analysis model which could be employed as an interface reinforcing cooperation between individuals of the architectural and engineering disciplines. The ultimate aim of this analysis model is to enhance urban system capacity to cope with the flood risk by including the spatio-temproal aspects of its management.
This analysis model is tested on the city of Taipei, between 1895 and 2010, which was regularly affected by flooding because of its geo-climatic conditions, especially sensitive to heavy rainfall.
