This study analyzed the characteristics of stormwater runoff by rainfall type in orchard areas for two years. Effluents were monitored to calculate the EMCs and runoff loads of each pollutant. The runoff characteristics for nonpoint sources from vineyards were also inspected based on independent variables that affect runoff such as rainfall and rainfall intensity. The average runoff loads of each pollutant from vineyard_A and vineyard_B were found as follows: BOD 39.13 ㎎/㎡, COD 112.13 ㎎/㎡, TOC 54.98 ㎎/㎡, SS 1,681.8 ㎎/㎡, TN 18.29 ㎎/㎡, and TP 4.06 ㎎/㎡, which indicates that the COD`s runoff load was especially high. The average EMCs from vineyard_A and vineyard_B, which represents the quality of rainfall effluent, were also analyzed: BOD 3.5 ㎎/L, COD 11.5 ㎎/L, TOC 5.2 ㎎/L, SS 211.7 ㎎/L, TN 1.774 ㎎/L, and TP 0.324 ㎎/L. This suggested that the COD, as an indicator of organic pollutants, is high in terms of EMCs as well. As rainfall increased, the EMCs of BOD, COD, TOC and SS kept turning upward. At a point, however, the high rainfall brought about dilution effects and began to push down the EMCs. Higher rainfall intensities led to the increase in the EMCs that displays the convergence of rainfall. Low rainfall intensities also raised pollutant concentrations, although the concentrations themselves were slightly different among pollutants.
