The Development of Flood Damage Functions for Public Buildings Using Damage Data and Field Surveys

Abstract

Flood damage assessment is an important factor in flood risk management. Flood depth damage functions are commonly used to estimate flood damage. Major developed countries such as the US, Japan, and those of Europe have developed flood damage estimation models based on damage analyses of past flood cases as well as the judgment of flood experts. However, such damage procedures are not applicable to Korea, because they are based on data from regions in other developed countries. To solve this problem, this study developed damage functions using actual damage data from public buildings in Korea. Damage rates were calculated for each type of public building by utilizing various damage data obtained from the mutual aid association and the building register, and data on the depth of flooding, obtained through field surveys. The damage function can then be used to analyze the cost-effectiveness of flood damage reduction measures. Keywords: Damage Function, Public Buildings, Flood Estimation Model, Field Survey
