Estimation of the Inflow Pollutant Loads for the So-okcheon Watershed using BAWAST Model

DAWAST 모형을 이용한 소옥천의 유달오염부하량 추정

A relationship between the water quantity and the inflow pollutant loads of BOD, TN, and TP in So-okcheon of the upper Keum river in 2000 was investigated in this study. Daily streamflow of So-okcheon needed to compute the pollutant loads was estimated by the DAWAST model, because there is no measurement of the discharge. From a relative function of the inflow pollutant loads using DAWAST, BOD can be estimated by the relation of $y=145.31x^{1.06},\;TN\;by\;y=598.11x^{0.90}\;and\;TP\;by\;y=39.60x^{0.89}$.
