Abstract
Recent years, impact of flooding damage in urban area is getting more serious and complicated than the past. However flood research in Taiwan emphasizes on natural hazards and natural vulnerability of rivers rather than human system in structure of natural disasters. The aim of this study is to generalize characteristics of happening flood disasters phenomenon, and to find out human vulnerability factors accumulating through decades of urbanization and those effects toward floods in order to response happening disasters.
Therefore, this study contains two research topics, “urban flood” and “human vulnerability factor” toward urban flood. In the first part, disasters history research is adopted for discussion of “urban flood” by analysis of 26 major flood events in Taipei Basin since 1960 to 2000 and case study. The second part takes disastrous and rapidly urbanized Shijr area as an example, analyzes each “human vulnerability factor” through comparison between simulating development conditions (1986, 1994, 2001) and corresponding typhoons (1987 Lynn, 1997 Winnie, 2000 Xangsane) in three different periods of time in a model which can integrate aerial photo maps, data resource, damage loss estimation and peak flow increase rate calculating.
It concludes that: flood disasters in Taipei Basin since 1996 gradually reflects “urban flood”, and the characteristics such as flood types, inundated locations and flooding damage are also shown apparently in certain Asian city like Tokyo, Fukuoka and Seoul; furthermore, “human vulnerability”, which might arouse possibility of flood disasters, weaken ability against flood disasters, and accumulate through urbanization of its character, contains four main factors cause of urbanization as follow: way of development, public flood-control construction, density of property spatially, ability against urban flood of property.
