碩士 === 國立臺灣大學 === 環境工程學研究所 === 89 === NPSM, a non-point source model, was used to simulate the Diyu chi basin located in Feitsui reservoir catchment and the requirement of information and suitability of parameters were investigated. Furthermore, continuous data on suspended solid loading is limited in Taiwan, therefore an optical device was developed to monitor the turbidity continuously and the information was used to estimate the concentration of suspended solid in the stream. By calibrating with data of 1997 and verifying with data of 1998, the prediction of the daily flow is good and that of the suspended load is reasonable. Capability of the new turbidity monitoring device which may be operated from 6.5 to 400 mg/L or better is verified and the device could be operated with independent power source for its low energy requirement.
