Resumo

Using a systems approach, a city can be considered as a complex system divided into several subsystems. Each of these systems require numerous regulations which enable the actors, at all times, to maintain or reestablish desirable urban functions during/after disruption from external events such as natural hazards. In this sense, flood risk could be considered as one of elements which can trigger urban regeneration. Among urban subsystems, our research focuses on the urban spatial morphology (USMS) which is made of geographical, physical and societal components. Surrounded by steep hills on three sides, Taipei is located on the floodplain of the Danshuei River. According to historical records, typhoons sweep through Taiwan around 3 times per year. With these geographical characteristics, the city has endured several floods and become more resistant to flood risks by adopting various adaptive regulations and measures. In this paper, a description firstly is given to show how floods caused by typhoons promoted interactions between components of the USM during 1895-1945. Secondly, a demonstration exposes that adapted architectural and urban planning regulations protected the city from flood risks. Finally, an analysis of the City's Master Plan displays that flood risk became one of key components of urban structure.
