Predictions of stream water quality require both estimation of pollutant loading from different sources and simulation of water quality processes in the stream. Nonpoint source pollution models are often employed for estimating pollutant loading in rural watersheds. In this study, a conjunctive application of SWAT model and WASP model was made and evaluated for its applicability based on the simulation results. Runoff and nutrient loading obtained from the SWAT model were used for generating input data for WASP model. The results showed that the simulated runoff was in good agreement with the observed data and indicated reasonable applicability. Loading for the water quality parameters predicted by WASP model also showed a reasonable agreement with the observed data. It is expected that stream water quality could be predicted by the coupled application of the two models, SWAT and WASP, in rural watersheds.

For the assessment of the level of stream pollution, SWAT -WASP model linked with GIS was applied to a representative rural watershed and evaluated for its applicability through calibration and verification using observed data. Using daily water yields, sediment yields and nutrient discharge simulated by SWAT model, WASP input file was build. Point source pollutant and water quality change in stream was considered in WASP model. For the model application, digital maps were constructed for watershed boundary, land-use, soil series, digital elevation, and topographic data of Bok-Ha watershed using GHASS. The model application results showed that the simulated runoff was in a good agreement with the observed data and indicated reasonable applicability of the model.
