| Popis: | Natural disasters caused by climate change frequently occur around the world. In Korea, flood warnings and storm warnings are used to prepare for flood damage. However, flood warnings are specifically issued for rivers while storm warnings use the same criteria throughout the country. Accordingly, there is a limit to effective flood preparation which reflects the regional characteristics of each administrative district. In this study, the flood risk matrix for each administrative district is developed in order to provide flood risk forecast information that reflects upon local characteristics. Moreover, the applicability is evaluated by using dichotomous forecasting. As a result of the forecast's evaluation, the probability of detection was determined to be over 80%. Therefore, it is possible to prepare for a flood through the forecast information of the administrative district using the flood risk matrix. In the future, it will be necessary to study how to improve the utilization of flood risk forecasting information through the continuous investigation of past damage phenomenon along with a review of flood-influencing factors. |
