Recently, Global warming and abnormal climate problem are urgent global issue. Due to such problems represent heavy storm and rainfall. Therefore, natural disasters and floods are increased every year in Korea. This study analyzed change characteristic of Probable Rainfall according to the different sample size in Deagu. And, Frequency analysis carried out 5 parts by 1961-2013 rainfall data period being divided 10-yr(1961-1970, 1961-1980, 1961-1990, 1961-2000, 1961-2010). At the result of frequency analysis, the probable rainfall depth could confirm the increasing trend. When the hydraulic structures are to be designed, it is important to select the data size and necessary to re-estimate the flood prevention capacity in existing river systems.
