4. CONCLUSION In this study, Vulnerability Ranking of hydrological safety was ranked using MCDM method in climate change scenario. MCDM technique is difficult the choice of one way due to the differences in the advantages and disadvantages of each method (Min and Song, 2003), However using the results of the various MCDM methods, it is considered to be able to take advantage of prioritization on Vulnerability Ranking for dam hydrological safety. In this study, dam I was calculated as the most vulnerable Dam I. When future peak flooding occurs, it is considered the most vulnerable due to the overflow of dam I. In comparison with other dams, It is considered necessary to take additional actions in the future to secure the remaining capacity of the dam.
