Abstract
In this study, the results from the analysis on the basic flood risk assessment items suggested in the long-term comprehensive plan for water resources were compared with the results from the analysis on the basic items and the index items added in consideration of regional characteristics of Gyeongsangbuk-do. The comparison results are summarized as follows. With the use of the flood risk assessment items suggested in the long-term comprehensive plan for water resources, the basic flood risk grades of the regions in Gyeongsangbuk-do were analyzed. The index items reflecting regional characteristics were added and then analyzed. The analysis results were compared. As a result of applying regional characteristics based on four conditions such as hydrology-geological, social-economic factors, flood control, and meteorological factors, the risk grades of many regions (about 30 %) were raised, but there was no significant change in the risk grades in the rest of the regions. When the index items that reflected regional characteristics were applied in the flood risk assessment, regions had different risk grades according to their regional characteristics in each factor. Therefore, such a method helped to suggest the direction of establishing improved water management measures.
