A Study on the Variation of Water Quality and Selection of Intake Station for Industrial Water Supply in Kumgang Estuary Reservior

This study was investigated to survey and forecast water quality for selection of intake station for industrial water supply in Kumgang estuary reservior. Variation of water quality in reservior was compared with before the sluice was closed and after. The best selection of intake station was in wachori, water quality was forecasted less than BOD 6mg / l (industrial water supply Ⅰ class) at 2021 year. Chlorophyll-a concentration was less than 5ug / l before the sluice was closed, but it was increased by maximum 60ug / l suddenly after the sluice was closed. The water quality of river have been changed that of reservior. Because chloride concentration were settled less than about 60mg / l after about two months the sluice was closed, they will do not matter in use of industrial water supply.
