Abstract

Flooding is a major type of disaster in Korea; urban flooding has especially become a serious issue as impermeable parts are increasing in urban areas. Local governments have established structural measures to reduce losses caused by urban floods; however, this can cause financial problems. Therefore, nonstructural measures are needed, and the basic information for the measures has to be clear. It is necessary to establish standards for loss estimation since prevention and recovery are a source of numerous expenditures in national finance. The United States, Japan, and Taiwan have representative methods for loss estimation based on their own databases related to loss information for critical disasters (e.g. earthquakes, storms, and floods). Korea also has some statistical tools – such as Multi-Dimensional Flood Damage Analysis – for national flood control economic analysis; however, there are no systematic lossestimation tools, mainly because of a lack of available data. In this study, previous research and techniques were reviewed to find adequate tools and frameworks applicable to loss-estimation methods for urban flooding in Korea. The availability of databases related to urban flooding in Korea was then checked. Keywords: flood, loss estimation, multi-dimensional flood damage analysis.
