본 연구에서는 금호강에 유입되는 지천에 대한 강우 및 무강우 시 모니터링 결과를 활용하여 수질평가를 통해, 강우 시 지천의 비점오염원 유출특성을 분석하고자 하였다. 금호강 유입지천의 수질 분석결과, 최상류에 위치한 신령천의 수질을 살펴보면, BOD 1.8 ㎎/L, COD 7.2 ㎎/L, SS 19.0 ㎎/L, T-N 4.629 ㎎/L, T-P 0.144 ㎎/L로 조사되었다. 다음 순으로 북안천 지점의 수질은 BOD 1.8 ㎎/L, COD 8.2 ㎎/L, SS 23.5 ㎎/L, T-N 2.858 ㎎/L, T-P 0.170 ㎎/L, 청통천 지점은 BOD 2.4 ㎎/L, COD 8.5 ㎎/L, SS 77.7 ㎎/L, T-N 3.988 ㎎/L, T-P 0.326 ㎎/L, 오목천 지점은 BOD 1.7 ㎎/L, COD 7.5 ㎎/L, SS 13.1 ㎎/L, T-N 3.505 ㎎/L, T-P 0.179 ㎎/L로 조사되었다. 청통천의 경우 T-P 항목을 제외하고는 다른 지점에 비해 오염도가 높게 조사되었으며, 특히 SS 항목의 경우 높은 오염도를 나타내고 있음을 확인 할 수 있다. In this study, the rainfall and non rainfall monitoring results for the tributaries flowing into the Gumho River was to analyze the runoff characteristics of the tributaries during the rainfall. Water quality analysis of incoming tributaries, in case of the Sinryungcheon was investigated by BOD 1.8 ㎎/L, COD 7.2 ㎎/L, SS 19.0 ㎎/L, T-N 4.629 ㎎/L, T-P 0.144 ㎎/L. Water quality of the Bukancheon and Cheongtongcheong and Omokcheon were investigated by BOD 1.8 ㎎/L, COD 8.2 ㎎/L, SS 23.5 ㎎/L, T-N 2.858 ㎎/L, T-P 0.170 ㎎/L and BOD 2.4 ㎎/L, COD 8.5 ㎎/L, SS 77.7 ㎎/L, T-N 3.988 ㎎/L, T-P 0.326 ㎎/L and BOD 1.7 ㎎/L, COD 7.5 ㎎/L, SS 13.1 ㎎/L, T-N 3.505 ㎎/L, T-P 0.179 ㎎/L. Cheongtongcheon was investigated pollution was high except for T-P compared to other sites. And particularly in the case of SS, it was investigated as representing the highest pollution.

낙동강 195개 지류․지천 지점에서 2015년 수집된 699회의 유량 및 BOD/COD/T-N/T-P/SS/TOC 농도 등의 수질 자료를 이용하여 중점관리지점 선정 연구를 수행하였다. 각 모니터링 지점에서 BOD, T-P, TOC 농도 및 오염부하량에 대한 변동계수가 매우 크게 확인되어 1년 평균 자료를 이용한 중점관리지점 선정이 경우에 따라 불합리할 수 있을 것으로 지적되었다. 이러한 이유로 본 연구에서는 각 모니터링 자료를 평균화하지 않고 독립적으로 이용할 수 있는 두 가지 방법을 제시하였다. 첫 번째 방법으로 각 모니터링 시점별로 수집된 BOD, T-P, TOC 농도를 낙동강 중권역별 목표수질과 비교하여 목표수질을 초과하는 횟수를 각 지점별로 산정하였다. 두 번째로 BOD, T-P, TOC 항목에 대한 오염부하량을 각 모니터링 시점별 및 지점별로 산정하여 % 순위를 산정하는 방법을 적용하였다. 이상의 방법을 통해 결정된 중점관리지점을 서로 비교하였으며, 이를 통해 낙동강 유역의 수질의 전반적 특성을 분석하였다. Water quality data including flow rates and BOD/COD/T-N/T-P/SS/TOC concentrations in Nakdong river tributaries were analyzed to determine priority management areas using 699 data sets from 195 locations in 2015. It was pointed out that the coefficients of variation, the ratio of the standard deviation to the mean, for the concentrations and loading rates of BOD, T-P, and TOC in each monitoring location were so large that average values of water quality monitoring data might be not appropriate to determine the priority management areas among all 195 monitoring stations in Nakdoing river. Therefore we suggested two evaluation methods using each water quality data independently. In the first method the excess numbers of the BOD, T-P, and TOC concentrations comparing to the water quality standards in the medium-sized management areas in Nakdong river was evaluated for each monitoring station. In the second method the percentile ranks of the loading rates of the BOD, T-P, and TOC were obtained for each monitoring data. The two groups of the priority management areas determined by each method were compared and the water quality characteristics in Nakdoing river were investigated.

Water quality in Nakdong river was analyzed using 699 monitoring data sets including flow rates and water quality concentrations collected at 195 tributary monitoring stations (the priority management areas: 35 stations, the non-priority management areas: 160 stations) in 2015. The highest average concentrations of all data for BOD, COD, T-N, T-P, SS, and TOC were 30~600 times higher than the lowest concentrations while the highest average loading rates were 800,000~2,700,000 times higher than the lowest loading rates. Because of the very large differences in the concentrations and loading rates, the variation of the concentrations and loading rates in a priority management monitoring station for BOD, T-P, and TOC was analyzed using the coefficient of variation, the ratio of the standard deviation value to the mean value. For BOD, T-P, and TOC, the coefficients of variation for concentration were mostly less than 100%, whereas the coefficients of variation for loading rate ranged from 31.1% to 232.2%. The very big difference in the loading rates was due to the large variation in flow rates. As a result of this, the estimation of water quality at each monitoring station using the average values of the concentrations and loading rates might be not rational in terms of their representativeness. In this study, new water quality analysis methods using all collected monitoring data were suggested and applied according to the water quality standard in medium-sized management areas.
