AGNPS 모델에 의한 비점오염원으로부터 하천으로 유입되는 오염부하량 예측 = Prediction of Influent Pollutant Loads into the Rivers from Nonpoint Source by AGNPS Model

다국어 초록 (Multilingual Abstract)

To predict the pollutant load from non-point source of agriculture basin, AGricultural Non-Point Source(AGNPS) was applied for small river of Gaeun Chun located at Sangju city. The applied basin area had the cultivation area of about 41% such as rice paddy field, patch, and orchard and the forest area of 58.7%. Observed peak flow rate during July to September 2002 were 0.026㎥/sec∼9.265㎥/sec for P-1, 0.01 O㎥/sec∼2.747㎥/sec for P-2 and 0.064㎥/sec∼13.482㎥/sec for P-3. The concentration of total nitrogen(T-N) and total phosphorus(T-P) were 2.80∼10.70㎎/L and 0.25∼1.84㎎/L for P-1, 2.70∼8.90㎎/L and 0.27∼1.9l㎎/L for P-2, and 2.80-9.70㎎/L and 0.25∼1.79㎎/L for P-3, respectively, which indicated the small river was considerably affected by non-point source. The simulation results of the AGNPS were given in the correlation equations from the observed and calculated values as follows: TNc= 1.3885 TNo^(0.7864)(R2=0.894) and TPc=1.2399 TPo^(0.9459) (R2=0.794).
