Analysis of Heavy Rain Damage Considering Regional Characteristics

Abstract

There is a difference in heavy rain damage depending on the geographical characteristics and population size of the local region. Therefore, in this study, the areas were classified as 6 regions according to geographical characteristics and population density. And the frequency analysis was conducted based on annual damage data occurred by heavy rainfall. The 6 regions mean Coastal-High population density, Coastal-Low population density, Mountain-High population density, Mountain-Low population density, Inland-High population density, and Inland-Low population density areas. In other words, we can obtain the relationships of 4 types between frequency and damage such as High frequency-Big damage (Red zone), Low frequency-Big damage (Orange zone), High frequency-Small damage (Yellow zone), and Low frequency-Small damage (Green zone) from the frequency analysis of heavy rain damage. Therefore, if we use the analysis result of heavy rain damage according to regional characteristics suggested in this study, we can establish efficient disaster planning and management for each region.
