Abstract

This study was performed to investigate the stream water quality characteristics in the Dowoncheon basin of Dongjin River during the 12 months from January to December in 2005. Also, pollutant loads were calculated on the basis of the water quality and runoff results. The measured pH and EC of the stream water were ranged 6.48 7.32, 18.06 38.60 S/cm, respectively. The concentration of DO, BOD, COD, SS, T-N and T-P were observed as 4.90∼11.50 mg/L, 0.5∼6.0 mg/L, 1.22 18.46 mg/L, 1.0 2,124.0 mg/L, 1.35 5.67 mg/L, 0.02 0.43 mg/L respectively. T-N showed low correlativity with other water quality parameters. However, T-P had very high correlativity with COD and SS. In the meantime, the runoff pollutant loads of T-N, T-P were estimated as 72,114 kg/yr, 5,027 kg/yr. In the case of the correlativity between runoff pollutant loads and concentrations, T-N did not show significant relationships, while T-P had significant relationships.
