다국어 초록 (Multilingual Abstract)

The Stochastic Time River Elevator Approach Mode (STREAM) which is a multiconstituent stream ecosystem model was exclusively developed in this study. The formulation of STREAM is based on the Cell-In-Series (CIS) approach where stream is assumed as a series of completly mixed flow reactors. This approach is to use a Lagrangian coordinate instead of an Eulerian such that it can overcome the limitations repoted in the previous stream models, such as QUAL2E. Major constituents included in STREAM are Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Suspended Solid (SS), Coliform Bacteria, Nitrogen Series, Phosphorus Series, and Phytoplankton. Dissolved oxygen change caused by Sediment Oxygen Demand (SOD) and respiration and photosynthesis of periphyton and macrophyte are included in the model structure. STREAM was programed in a BASIC language and graphic was attached. In order to validate STREAM model, both STREAM and QUAL2E (developed by United States Environmental Protection Agency) were applied to the South Branch of Han River under the same amibient condition. The result indicated that STREAM could simulate most water qualities with same accuarcy and less computer time than QUAL2E.
