초록

This study has performed comparative analysis on characteristics of reservoirs in their use through correlation analysis on seasonal variation of water quality factors in agricultural reservoirs and multipurpose dams. Agricultural reservoirs show the high relationship between Chl-a and other water quality factors while the correlation among COD, BOD, and SS is strong in multipurpose dams. Agricultural reservoirs have the high relationship between various water quality factors in season such as Chl-a and pH (R2=0.294) in Spring, pH and water temperature (R2=0.246) in Summer, and Chl-a and BOD (R2=0.435) in Fall, and between COD and BOD (R2=0.370) in Winter, respectively, for Sapgyo reservoir while Chl-a and T-P (R2=0.739) in Spring, T-P and SS (R2=0.876) in Summer, and Chl-a and SS (R2=0.600) in Fall, and between COD and SS (R2=0.998) in Winter, respectively, for Seokmun reservoir. Boryeong dam has the strong relationship between T-P and SS (R2=0.511) in Spring while the relation between COD and SS is high in other seasons with the values of R2 of 0.362, 0.665, and 0.500 in Summer, Fall, and winter, respectively. The first and second water quality factors in relationship are COD and BOD in Sapgyo and Seokmun reservoirs, which is similar to the characteristics in Winter for multipurpose dams. Chl-a has no relationship with other water quality factors in Boryeong dam in operation for both flood control and low water regulation purposes. The result of this research is expected to provide contributions to the seasonal water quality control and analysis on characteristics for each reservoir by monitoring.
