Abstract

Multidimensional dynamic water quality model of organic matter and trophic state was applied to the Han River system. The model was calibrated using field measurement data obtained during the year of 2007. The model results showed reasonable performance in predicting temporal variations of TN, TP, Chl-a and BOD concentrations. The applied integrated modeling system can be effectively used to simulate water quality as well as hydrodynamic and water temperature for river-lake continuous system in the Han River. Utilizing the calibrated model, we analyzed the spatial and temporal distributions of TN, TP, Chl-a and BOD concentrations in the Han River system. The temporal variations of water quality at each river reach and lake were effectively simulated with the developed model and spatial distribution of water qualities in the Han River system could be compared. The multidimensional dynamic modeling system can simulate the water qualities of entire waterbody where Lake Paldang and the incoming flows are included using single modeling system. So it can be effectively used for integrated water quality management of the Han River system.

본 연구에서는 한강수계에 대하여 다차원 시변화 유기물 및 영양상태 모델을 적용하여 2007년에 관측된 수질 자료를 이용해 그 재현성을 검토하였다. 모델 적용 결과 TN, TP, Chl-a, BOD 농도의 시변화를 모델이 적절히 재현하고 있는 것으로 나타났다. 따라서 본 모델 시스템은 한강수계 내 하천-호수 연속 시스템에 대하여 수리 및 수온 해석뿐만 아니라 유기물 및 영양상태 해석에도 적용이 가능한 것으로 판단된다. 모델 보정 결과를 바탕으로 TN, TP, Chl-a, BOD에 대한 한강수계 내의 시 공간적 농도 변화를 분석하였다. 모델은 호수 구간 표층과 하천 구간에 대하여 각 구간별로 수질의 시변화를 적절히 모의하였고 이를 통하여 한강수계 내의 공간적 농도 분포를 비교하는 것이 가능했다. 본 연구에서 구축한 다차원 시변화 모델 시스템은 하나의 모델로 팔당호와 그 상류 수계의 수질을 통합적으로 분석하는 것이 가능하므로, 한강 수계에 대한 통합적인 수질 관리에 효과적으로 사용될 수 있을 것으로 기대된다.
