The natural disasters such as floods and droughts have been severely occurred in Korea. So, this study tried to suggest the procedure for frequency analysis of the future rainfall, snowfall depth, and wind speed. The design criteria were estimated based on the frequency analysis for each hazard under the climate change. We compared the current design value and the future value then investigated the design criteria of structural measures for the future. Based on the climate change analysis, we have shown that the future rainfall and wind speed will be increasing but the snowfall depth will be decreasing.
