초록

In this study, the load of the river was calculated by using the actual data of the Yeong-bon C1, Yeong-bon C2, Yeong-bon C3monitoring points of the Yeong-san river watershed to determine the excess. As a result, the BOD is 75.83 % at the Yeong-bonC1 and the five-year average value is higher than at other points. The Yeong-bon C3 was 72.15 % and Yeong-bon C2 wasanalyzed as 68.78 %. The five-year average of the T-P was 71.95 % for the Yeong-bon C2 and 69.86 % for the Yeong-bon C3and 69.16 % for Yeong-bon C1; these levels exceeded the target water quality standards of 50 %. As a result of analyzing thepollutant load, we found that the Yeong-bon C1 has been highly affected by the nonpoint pollution source because the excessrate is high in the upper section of the flow rate. The Yeong-bon C2 showed a high excess rate in the lower part of the flowrate, and it was estimated that the influence of the point pollution source was large. The excess rate of the Yeong-bon C3 issmall in the interval deviation, and it was evaluated as being affected by both point and non-point pollution sources. TheTMDL monitoring network data were used to estimate the exceed ratio for the target water quality assessment, and theimplementation evaluation was made by the flow exceedance probability interval to analyze the monitoring data so that thedata could be utilized according to the purpose of the measurement network.
