SIREM1 모델을 이용한 수초에 의한 하천 수질 변화 분석
박석순,홍헌표 ( Seok Soon Park,Heon Pyo Hong ) 한국물환경학회 1997 한국물환경학회지 Vol.13 No.2
Water quality changes caused by macrophytes was quantitatively analyzed in this paper, using SIREM1 model. The model was calibrated and verified to water quality data collected from Tan stream where an excessive growth of macrophytes was observed in upstream area. The water quality parameters included in the model were dissolved oxygen(DO), carbonaceous biochemical oxygen demand(CBOD), and nutrients. Diurnal dissolved oxygen was simulated using QUAL2E model developed by USEPA as well as SIREM1 model. The results from SIREM1 model showed good agreement with field measurements. However, QUAL2E model could not represent the fluctuation of diurnal dissolved oxygen. Model sensitivity was analyzed with regard to several parameters which include temperature, reaeration coefficient, photoperiod, and light intensity. The role of macrophytes in the water quality changes was examined. The results indicated that macrophytes played an important role of controlling diurnal dissolved oxygen variations, nutrient uptake/recycle, and the generation of autochtonous organic matter. It was concluded from this study that SIREM1 model could effectively simulate diurnal dissolved oxygen and other conventional water qualities in macrophyte dominated stream.
