Water Quality Modeling for Integrated Management of Urban Stream Networks

Abstract

This study presents a water quality Management program for Urban River Networks (WAQUMURIN). The model analyzes a variety of water quality problems in urban stream networks linked by ponds, lakes, and reservoirs, which are subdivided into unit reach cells. A mass balance is performed in each cell for the nonconservative contaminants loaded from point and nonpoint sources on land. The model was designed by GUI to provide a practical program for management purposes. To test the performance of the model, it was applied to the Han River network in the city of Seoul, Korea, which has eight stream branches. The test was conducted for BOD load and compared with measured data.
