This project was scheduled from March 20th, 2003 to December 31st, 2003. This project has accomplished tasks such as estimating of BOD-COD-NH3 quantity for pollutants, selecting of target pollutants and monitoring stations, simulating water quality & analysis of load capacity, amending for management of pollution sources and planning of water quality monitoring. This project has developed water quality information of computerized system for Jhongkong River, Nankan River, Keya River & Wu River. The system is provided consultation of strategic decision for pollution control and reduction. This project has developed decision support system which combined several models such as estimating model of pollution quantity, estimating model of reducing pollution quantity, Qual2E water quality model, Alternative choice coefficient, cost estimating model. Moreover, this project evaluated realistic remediation programs by the weight of factors, which decided on 107 inquiring letters. This project has applied decision support system to plan remediation programs for four rivers. It applied the models of this system to simulate water quality for short-term stage, intermediate stage and long-term stage. It could provide decision-maker for evaluating water quality improvement of each remediation program.
