낙동강 보 설치구간의 부영양화 관리를 위한 인공습지 적용가능성에 관한 연구

Abstract

This study investigated the trophic state of Nak-Dong River for eutrophication management and deducted limiting foctor. When managed the eutrophication by the artificial wetland, the calculated artificial wetland was examined the possibility of applying. The eutrophication between Gu-mi dam and Ham-an dam in construction site of the dam of the Nakdong river was higher than other sites. So required area of artificial wetlands for Geum-ho river and Gam stream were 21,959 ha, 7296 ha, respectively. which is 34%, 8% of total watershed area. It is impossible to apply the artificial wetland. So when applying discharge water of environment fundamental facilities, the required areas of Geum-ho river and Gam stream were 1940 ha, 179 ha, respectively , which is 3%, 0.2% of total watershed area.
