Abstract
This study identified key management target water quality constituents reflecting watershed characteristics and evaluated water quality characteristics through multivariate statistical techniques targeting the Gwangju, Manbong, and Munpyeong stream watersheds of the Yeongsan River basin. The main components for the water quality factors were nutrients in Gwangju Stream and Munpyeong Stream, and organic matter in Manbong Stream, respectively. Cluster analysis over time for water quality classified into 2 groups for Gwangju Stream, but Manbong Stream and Munpyeong Stream were classified into 5 and 4 groups, respectively. Temporal changes due to agricultural activities were assessed to contribute to clustering. The main water quality factors and the time of inflow of water quality constituents are different depending on the characteristics of the watersheds. Therefore, it should be considered in the watershed management for stream water quality.
