The aim of this study is to allocate the amount of discharging pollution loads according to the main pollutants such as population, livestock, soil, industrial facilities of Yugu basin which is a branch of Geumriver. Also, the object area was divided into 22 small subbasin sectors to assess the loading amount and applicate the water quality model. The considering items to forecast the water quality were restricted BOD, TN and TP which had affluent data relatively. And only BOD data was used to calculate unit loading amount of the basin and arrangement of optimum pollution load. As a calculating result for the amount of discharged pollution load based on the pollution sources and data, the loading amount and density of the basin became the highest after joining of Yugu and Magok. And the results of the expected loading amount indicated the increase rate of load occurrence was less than average ±1.5% per year for BOD, TN and TP. So, it was known that factors such as population, livestock and industrial transformation kept up as present. The flow running rate for the small drainage sector by the running load amount was highly analyzed TP, BOD and TN in order. And the running load amount was high in case small basin and short running length. Also, BOD contribution rate was large as near the length for the end point of the stream and high pollution influx. The running load amount was 629.85kg/d and permission load amount was 483.03kg/d at the end of Yugu basin. Therefore, it is considered that the amount is to reduce 146.82kg/d and reduction load amount by the region on establishing the sewage treatment facilities was expected 185.07kg/d for Yugu, 22.21kg/d Shinpoong, 25.91kg/d Sagok, 20.26kg/d Woosung and 255.40kg/d after total same time reduction. So, it is concluded that the arrangement of optimum load amount for reduction is proper to Yugu, Sagok, Shinpoong and Woosung orderly.

수질오염 총량관리 제도의 시행계획 수립을 위하여 유역에서 배출되는 인구, 가축, 산업 및 토지이용 등 다양한 오염원에 의한 수질오염 부하를 최적 할당하기 위한 목적으로 본 연구는 수행되었다. 대상지역은 유구천 유역으로 부하량 할당 및 수질 모의를 목적으로 주요지천 및 본류직접 유입구간을 중심으로 22개 소유역으로 구분하였다. 수질모델링 및 평가항목은 BOD, TN, TP였으며 총량관리를 위한 오염부하 할당항목은 BOD로 국한하였다. 소구역별 발생오염원, 배출부하랑을 실측 수질 및 유량자료를 토대로 산정하였으며, 각 배수구역의 배출오염부하량이 오염총량관리 목표지점인 유구천 말단부에 미치는 기여율을 계산하였다. 환경기초시설에 의한 오염물질의 비용, 소배수구역별 기여율 등을 토대로 삭감대상 우선순위를 결정하여 배수구역별 최적 오염부하를 할당하였다. The aim of this study is to allocation pollution loads according to the various pollution sources such as population, livestock, soil, industrial facilities of Yugu Basin. The object area was Yugu Basin that a branch of Geumriver. Also, it divided into 22 small subbasins to assess the loading amount and applicate the water quality model. The considering items to forecast the water quality and model application were restricted BOD, T-N and T-P that is affluent data relatively. And only BOD data used to calculate unit loading amount a the basin and arrangement of optimum pollution load for TMDL(Total Maximum Daily Load). As a calculating result of the amount for the discharged pollution load using the pollution sources and unit data, the loading amount and density for the basin after joining of Yugu and Magok stream was the highest. And results of the expected loading amount indicated the increase rate of load occurrence was less than average ±1.5% per year for BOD, T-N and T-P. So, it was known that factors such as population, livestock and industrial transformation kept up as present. The flow running rate for the small drainage sector by the running load amount was highly analyzed T-P, BOD and T-N in order. And the running load amount was high in case small basin and short running length. Also, BOD contribution rate was large as near the length for the end point of stream and high pollution influx. The running load amount was 629.85kg/d and permission load amount was 483.03kg/d at the end of Yugu basin. Therefor, it is considered that the amount is to reduce 146.82kg/d and reduction load amount by the region on establishing the sewage treatment facilities was expected 185.07kg/d for Yugu, 22.21kg/d Shinpoong, 25.91kg/d Sagok, 20.26kg/d Woosung and 255.40kg/d after total same time reduction. So it is concluded that the arrangement of optimum load amount for reduction is proper to total reduction, Yugu, Sagok, Shinpoong and Woosung orderly.
