ABSTRACT

Since 1981, Youngsan river bank has become hollow and its water management has become ineffective. Following the project revitalizing the four major rivers in Korea that started in 2008, it is necessary to establish a new water management system due to the increase in the number of water structures. In this study, the SSARR model was selected to simulate the water circulation process at Youngsan river watershed, and the water circulation system for the Youngsan lake was established using the observed input data. The parameters calibration was performed from 2008 to 2009, which was verified with the data from 2013 to 2014. According to the varication with the 2013-14 data, the average absolute error of the last three stations was 4.7㎥/s in 2013 and 7.8㎥/s in 2014, respectively. The water circulation system applied in this study could help carry out an efficient water management of freshwater lake in Korea.
