This study was conducted to investigate runoff characteristics of non-point pollutants source in the paddy field watershed and small urban area in boeun area, Chungbuk Province. The paddy field watershed covering the watershed of 1.56 km2 contains about 44.4 % of total watershed with the paddy field and the small urban area covering the watershed of 2.11 km2 contains about 40.3 % of total watershed with the small urban area. The monitoring was conducted with six events for five months and Event Mean Concentration(EMC) and Site Mean Concentration(SMC) of SS, BOD, CODMn, T-N, T-P were calculated on the result of the water quality parameters. As a result of the comparion between Arithmetic Mean Concentration and Event Mean Concentration, it showed that over all Event Mean Concentration was higher than Arithmetic Mean Concentration. And it showed that SS, BOD, T-P featured the first-flushing effect, showing relatively high concentration in early-stage storm event.
