Abstract

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.
