영문 초록

The influences on water quality of each river by effluents from environmental facilities located * in 14 unit watersheds of h-and South-Han River, and Gyungan-cheon were analyzed. Also, the water quality modeling for study area was carried out to analyze the improvement effect of water quality by the strengthening of T-P effluent standard of environmental facilities. For the calibration and verification of model, water quality data and effluent loading calculated for 2006 were used. Data of low water period were used for calibration, and normal water period for verification. The results of calibration and verification were well matched with the real water quality dataset of revers. Also, the validity of the results were estimated using RI (Reliability Index) method. When the T-P effluent standards for environmental facilities were strengthened, T-P concentrations were predicted to improve from 0.025㎎/ℓ to 0.023㎎/ℓ in the outlet location of North-Han River, from 0.056㎎/ℓ to0.040㎎/ℓ for South-Han River,and from 0.233㎎/ℓ to0.146㎎/ℓ for Gyungan-cheon. Also, the T-P concentrations of tributaries including Jojong-cheon, Dal-cheong, Sumgang, Chungmi-cheon, Bokha-cheon, Heuk-cheon, and Wonju-cheon were predicted to improve from 0.063㎎/ℓ to0.010㎎/ℓ, from 0.091㎎/ℓ to0.053㎎/ℓ,from 0.199㎎/ℓ to0.100㎎/ℓ,from 0.168㎎/ℓ to0.148㎎/ℓ, from 0.186㎎/ℓ to0.105㎎/ℓ,from 0.019㎎/ℓ to0.013㎎/ℓ,and from 0.822㎎/ℓ to0.236㎎ /ℓ,respectively.
