Korea has a large seasonal deviation of rainfall and 65% of the national land is formed of
mountainous topography, and thus, has disadvantageous conditions for water resource
management in comparison to other countries. Further, the climate change caused by frequently
occurring severe floods and droughts is increasingly causing a lack in domestic water resources
and increased preponderance of rainfall. Together with such climate change, the increase in
water demands due to the development of scientific technologies and social aspects has
exceeded a scope that can be covered by the current water management system. This study
has selected SSARR as the basic model to evaluate a plan of supply and demand
management to resolve the lack of water in specific regions, and has prepared a water flow
system in the region of Youngjong-do, to perform water flow analysis, which has enabled the
comparison of the predicted water flow in 2014 using climate change scenario RCP 4.5, 8.5
and observed water flow from 2011 to 2014 year. These results will be used for quantitative
evaluation of climate change impact in order to minimize the damage. it can be used for
stable water supply considering continuously increased water demand through systematic and
efficient water resource management, which requires.
