| Popis: | The main reasons behind the occurrence of floods are climate change and rapid urbanization. Floods bring heavy casualties and enormous property damage. Therefore, a lot of support and flood-defence policies should be implemented and indexes should be developed in an effort to figure out the flood vulnerability. This study will investigate and analyse these indexes and consider Korean regional features to develop an index suitable for Korea and estimate its flood vulnerability. For this purpose, 115 subbasins in Korea were selected, and data related to regional flood losses from 1990 to 2007 were investigated to establish a database of the flood-related proxy variables for the period. In order to confirm the validity of the evaluation index, the results of Gangwon province from the calculated flood vulnerability assessment index (FVAI) are compared with actual flood damage records in 2008. Encouraged by this, FVAI was utilized as the means to estimate and present the regional flood vulnerability of Korea in the future. This study is expected to provide not only one of the various policy decision backgrounds, but also diversified information to better understand the current situation in Korea. |
