The objectives of this study are to simulate pollutant runoff from a small river basin in an urban area by using Water Quality Tank-Model, which can simulate it from a large river basin correctly, and to evaluate its accuracy for an urban river. As a result of the simulation, it was proved that Water Quality Tank-Model has a certain accuracy on solid pollutant in an urban area, but has less accuracy on soluble pollutant especially on soluble nitrogen. However, it was also proved that Water Quality Tank-Model could calculate integrated runoff pollutant load during a storm event, which was very significant especially in an urban river. In the result, it was cleared that a little more improvement made Water Quality Tank-Model more available to apply for the analysis of pollutant runoff from a small river basin in an urban area.
