초록

Characteristics of concentration of pollutants such as total nitrogen(T-N), total phosphorus(T-P) and chemical oxygen demand(COD) during dry days of $2002\~2003$ were investigated for streamwater from a rural watershed. Water was sampled and discharge was measured at 5-days intervals at outlet of study area. The mean concentrations of pollutants in non-irrigation and irrigation period not significantly different. For increasing discharge in 2002, TN concentration increased but COD concentrations decreases.
