The Forecasting of Chloride Concentration and Variation of Water Quality after Closing the Sluice Gates in Keum River Estuary Reservoir

This study was carried out to forecast the chloride concentration and to investigate the water quality for industrial water supply after closing the sluice gate in Keum river estuary reservoir. Chloride concentration was dilluted by input flow. depended on outside chlorine mass than inside mass from reservoir body. The forecasting equation for chloride concentration is got Ci = 3700·e^-0108ti + 405/√ti + 2.5 without considering input chloride concentration from upstream river. The water quality in intake station for industrial water supply was satisfied for the standard for industrial water supply. but requried the physico-chemical treatment owing to maximum values of turbidity, pH, TS, Fe, Mn were exceed the standard.
