담수호에 유입되는 하천수에서의 SS 와 COD 및 T-P 와의 상관관계

Correlation of SS to COD and T-P in Tributary to a Reservoir

When it rains, soil erosion occurs and soil particles move into the reservoirs or stream . Nutrients and contaminants, which are adsorbed on soil particles, flow into waterbody and are leached into water. Then they effect on water quality and eutrophicaltion of reservoirs. In this study , corrleation of SS to COD was surveyed , and that of SS to T-P was also done. R2 values in wet period were almost over 0.8, but were very low in dry period . THis shows that concentrations of COD and T_P will be assumed by using SS concentrations in wet period in stream.
