碩士 === 國立臺北科技大學 === 環境工程與管理研究所 === 99 === The present research delineated subwatershed in the PeiShih creek watershed by BASINS（Better Assessment Science Integrating point and Nonpoint Sources）, and then employed watershed models HSPF（Hydrological Simulation Program Fortran）and SWMM（Storm Water Management Model）to proceed hydrology and water quality simulations. The hydrology and water quality parameters were calibrated and verified with the hydrological data observed by the Taipei Feitsui Reservoir Administration, and the water quality data observed by the Taipei Water Management Office. The results showed that the average flow is 12.11 cms, the maximum flow is 348.87 cms, the average suspended solid is 8.1 mg/L, the maximum suspended solid is 382.0 mg/L, the average total phosphorous is 0.026 mg/L, the maximum total phosphorous is 0.155 mg/L for HSPF, and the average flow is 12.39 cms, the maximum flow is 269.75 cms, the average suspended solid is 17.2 mg/L, the maximum suspended solid is 124.2 mg/L, the average total phosphorous is 0.025 mg/L, the maximum total phosphorous is 0.120 mg/L for SWMM. HSPF and SWMM have similar simulation results, and then correlation coefficient（r）, coefficient of determination（R2）, nash sutcliffe efficiency（NSE） and mean percentange error（MPE）were within acceptable ranges. It also showed that the simulation results were reliable. Finally, sensitivity analysis of the major parameters belonging to the runoff, infiltration, sediment and total phosphorous transport control equations were discussed.
