Abstract
Water quality surveys has been performed to establish water quality improvement strategy for the lake Pyeungtaek, and WASP model was used to simulate to identify the effect of water quality improvement according to the reduction of pollutant loadings for the upstream watersheds. Assuming that present loadings was continued up to the future, the water quality of the lake was found to be getting worse resulting from the increase of pollutants due to the planned future development. In this study, we made various scenarios to predict the future water quality, scenario 6 made a large contribution to improve the lake water quality compared to others. Even the scenario 6, COD concentration of year 2016 in the lake was examined to be under the 4th rate of water quality level for the lake (COD less than 8 mg/L), similar to year 2021. Even though additional reduction of loadings for the scenario 6 was made, the water quality in lake was a little improvement, and was though to be inappropriate action in the economic point of view.
