Assessment of Climate Change Impact on Water Resources in Drought Prone Watersheds in Nakdong River Basin

This study investigated the climate change assessment on water resources with respect to precipitation and flow discharge over five multi-purpose dam watersheds in Nakdong River Basin. From the results of this study, it is found that the inter-annual variability of precipitation and inflow values is quite different among 56 projection. The precipitation and inflow trends toward the end of 21st century are diverse at five target watersheds. In general, precipitation trends are generally increased toward the early (3 similar to 4%), mid (8 similar to 11%), and the end (11 similar to 17%) of 21st century. The trends of inflow to dams are generally increased toward the early (4 similar to 5%), mid (8 similar to 11%), and the end (12 similar to 18%) of 21st century.
