Abstract
An integration study of time-variable small watershed and stream models (USEPA’s SWMMand WASP5) was performed for impact assessment of urbanization on water environment. Thestudy area, the Kyoungan Stream, the tributary of Paldang Lake, was divided into 111 sub-basins, based on the topographic condition, land use, and drainage system. RUNOFF block ofSWMM was applied to estimate runoff flow and quality. EXTRAN block computed daily andhourly flow according to simulated runoff flow, water supply, and drainage data. SWMM wasconnected to WASP5 by transforming output file of SWMM into input file of WASP5. The non-point source loads and flow data of SWMM were imported to WASP5. The stream was dividedinto 45 segments based on the watershed delineation. The study included three water qualityparameters, BOD, TN, and TP. The validate models were used to examine the impact ofurbanization on stream flow and water quality.
