AB - Recent increases in the frequency and intensity of concentrated heavy rainfall due to climate change have exacerbated heavy rainfall damages. Accordingly, this study targeted all cities, counties, and districts nationwide from 2014 to 2023, standardizing heavy rainfall damage amounts based on population, area, and GRDP using Z-Scores to classify regions by damage magnitude. High-risk regions exceeding the average across all three criteria were then selected, and frequency analysis was conducted by applying the Weibull formula to the time series of annual cumulative damage amounts. The analysis revealed that high-risk regions are concentrated in the upper, middle, and lower reaches of the four major river basins as well as some coastal and lowland areas, with these regions further categorized into large-scale low-frequency types and small-scale high-frequency types-demonstrating that even within the same high-risk areas, disaster patterns and required countermeasures differ. This multidimensional approach combining damage magnitude and frequency overcomes the limitations of conventional single-event damage magnitude analysis, providing policy grounds for differentiating priorities between structural flood control measures and everyday non-structural countermeasures, while contributing to enhanced efficiency in disaster management policies and the advancement of damage prediction models in the era of climate change.
