초록

The purpose of this study is to identify the continuously changing stream flow according to climate change through analyzing so that it can be used as ground survey data for current status of water source supply capacity of streams in the community and for possibility of future problems that may occur. About Bukcheon which is used as a water source in Sangju city, the river runoff was analyzed using the TANK model and at the same time, it was also analyzed using observation data. As a result of examining data for the analysis using the observation data, it was confirmed that the observations were carried out since 1942, and therefore a lot of data could be obtained. However, the water level-flow relationship curve to using those data was not developed and the data accumulated over a long period of time could not be used. Therefore, in this study, we analyzed the observation data using data from 2006, when the water level-flow relationship curve was developed. The TANK model analysis for comparison with the observed data was conducted from 1987 to 2016 using long-term runoff data using daily precipitation data. And the comparisons and analysis results using actual observation data were comapred from 2006 to 2016. Currently in Sangju city, Bukchon is used as a water source and it is confirmed that 12,600 m3/day(0.146 m3/s) of water is planned to be taken. As a result of analysis using actual observation data, Bukcheon stream flow rate is 0.062 m3/s. The analysis shows that the minimum water flow rate of 0.4317 m3/s, plus the maintenance flow rate, estimated using the data of the Long-term Water Resources Plan (2006~2020) (2006) should flow in order for Buckchon to function as a stream.
