Abstract
Pollutants discharge modeling was carried out in the watershed of Mankyung and Dongjin rivers. The watershed and pollutants source information extracted and analysed by the GIS tool was used as the model input parameters. This model was calibrated by comparison of the measured and computed monthly freshwater discharge and water quality(WQ) concentration. The compared WQ data are the ten-year-mean WQ concentration and monthly WQ concentration in 1999. The results show that the watershed runoff is underestimated in summer season, although the seasonal trends are relatively well estimated. The WQ concentrations were also relatively well estimated except Iksancheon. The computed concentration was much lower than the observed concentration in Iksancheon because of the effect of polluted sediment. Thus, the effects of polluted sediment on water column need further study through measuring and analysing the degree of the sediment contamination.
