In this study, a mesoscale atmospheric/hydrological model (IRSHAM96) and a water balance model are applied to predict the possible changes in hydrological conditions (precipitation, air temperature, runoff, etc.) in the Geum River basin, Korea. From the simulation results for 1×CO2 and 2×CO2 conditions, it was found that the precipitation, soil moisture and runoff would decrease in spring, winter and autumn, but increase in summer due to the increase in CO2. However, the air temperature and evapotranspiration amounts were found to increase in all seasons due to the increase in CO2. As a result, it was predicted that the frequency of drought and flood occurrences in the Geum River basin would increase due to global warming.
