100mm)) show that low flow increase in most of the sub-basins for 2031-2060 and 2061-2090. In the case of high flow, it have higher frequency ranging from -100% to 500% than low flow. Regardless of the variation of mean runoff, maximum discharge appeared to be increase in process of time. The regression method is used to figure out the relationship between the rate of runoff change and mean temperature, mean precipitation under A2 scenario. The mean actual evapotranspirations from the regression equations increased by 3.45.3% for the change of . Also, for the precipitation change of 10%, runoff variety range is -18.2+12.4% in Han River, -21.6+14.6% in Nakdong River, -17.5+11.5% in Gum River, -18.4+10.6% in Sumjin River, -19.9+12.7% Youngsan River basin.
