Water Quality Improvement in Nakdong River Subwatershed by Priority Selection

This study’s purpose is to establish the water quality improvement measures of the Nakdong River water system by determining pollutant sources and causes of the Nakdong river basin subwatershed (standard watershed). For this purpose, the water quality data of the inflow river according to the characteristics of the watershed are acquired for the eight dams of the Nakdong river system (Sangju, Nakdan, Gumi, Chilgok, Kangjeong-Goryung, Dalsung, Hapcheon-Changryung, Changryung-Haman) and obtained all the data necessary to identify the pollution sources. After identifying the current status and causes of pollution sources in the Nakdong River basin subwatershed (standard watershed), we selected priority to reduce pollutant load on subwatershed and improve water quality.
