ABSTRACT

The future climate projection based on international climate change scenarios expected that changes in hydrological circulation and the ecosystem would be inevitable in the future because of higher temperature and more rainfall events.Moreover, because the rapid urbanization and industrial development led accelerated land development and increased the impermeable layer’s size, the river water pollution caused by non point source(NPS) pollutants is expected to worsen(Ministry of Environment, Water Environmental Management Plan). The result of this study showed that, in the future, the number of rainy days would increase and the temperature would be 4℃ higher than the current temperature. As a result of these changes, runoff was expected to increase by 54% in the future. In terms of changes in NPS pollution loadings, BOD, T-N, and T-P were expected to increase by 216%, 54%, and 50%, respectively.
