中文摘要 | 水筒模式雖易於計算使用且對降雨-逕流模擬效果甚佳,然而由於其模式參數較多故常造成率定上的困難,因而彰顯了參數率定法建置的重要性。本研究以Powell法與SCE法之二自動化參數率定法來對付水筒模式之參數搜尋做一比較,結果發現Powell法收斂計算效率較高,且若能適切輸入參數初始值,其參數率定之結果並不亞於SCE法。但就使用的方便性與對參數之搜尋能力上而言,SCE法則有較佳的表現。 |
英文摘要 | Tank model is easy to use and it is effective in the rainfall-runoff analysis. However, it contains 16 parameters that increase the difficulty of calibration. For establishing an automatic calibration method for the tank model, two calibration methods-Powell method and SCE method, respectively, are compared in this paper. It is found that the SCE method is easier to use and has better ability to search for the 16 parameters of tank model. Nevertheless, if a of suitable initial values of parameters was put into the calibration, the Powell method may have higher efficiency in the calculation and may also have accuracy by comparison with the SCE method. |
