| Popis: | 85 The main purpose of this study is to analyze three rainfall-runoff models, unit hydrograph method, linear reservoir model and storage function method, that are suitable for watershed of Shihmen reservoir. The datas of typhoon in 1985-1996, are applied to estimate of three rainfall-runoff models. The result of unit hydrograph method show that calculated value is greater than observed value, and the coefficient of efficiency (CE) is among 0.22-0.81. The result of linear reservoir model show that calculated value is greater than observed value in both of the rising and regressing segment, and the coefficient of efficiency (CE) is among 0.46-0.85. The result of storage function method show that calculated value is closed to observed value, and the coefficient of efficiency (CE) is among 0.87-0.98. The analytical approaches adopted in this study are excepted to be used as important references to Shihmen reservoir administration, in the planning and the design of water resources utilization, watershed management and flood forecast in watershed of Shihmen reservoir. |
