| Abstract |
| This study aims to provide relevant data about the Osan-cheon water in order to improve the water quality and effectively run that water system. Chl-a and COD are respectively 24.14(mg/m3) and 7.51(mg/L) in Osan-cheon which indicates that the water quality is poor in it. It shows the characteristic of water contamination, which gets worse in the dry season since the amount of water lacks. The data about the water quality from the three different areas called state-level Osan-cheon, local-level Osan-cheon, and Shingal reservoir were collected and analyzed to reveal the correlation of Chl-a and water pollution factors. Several different data sources from 2008 to 2012 were examined. This investigation reveals that COD is strongly correlated with Chl-a in Shingal reservoir and state-level Osan-cheon. Mostly COD is correlated with other water quality factors throughout the regional research sites. The density of T-N, T-P, COD is higher in winter than that in summer in the research areas. Therefore, how to manage COD and how to manage water pollution factors in winter would be most important to efficiently manage rivers, lakes, and reservoirs. |
