| 中文摘要 | 本文以濁水溪支流清水溪流域及濁水溪主流集集流量站以下至西螺大橋間為範圍,進行濁水溪洪水預報數學模式之探討。本研究採用兩種數學模式;(一)以貯蓄函數法的流域演算配合馬斯金更法進行河道演算,(二)採用複相關法進行演算。模式中各參數值經過檢定後皆予統一,改善過去模式參數未能統一之現象可避免預報作業參數選用的困擾。兩種模式經過驗證後顯示結果良好,但以複相關較優,具有理論簡單,使用方便,爭取時效,預測準確之特性,值得採用。 |
| 英文摘要 | To find a suitable flood forecasting model for Cho-Shui River, two mathematical models are studied in this paper. One is storage function model for watershed routing plus muskingum method routing the river channel, the other one is multiple regression model. After calibrating these two models with field data, the model parameters are determined and fixed. In past studies the parameter values vary with each modeling. The fixed parameter values can eliminate the difficulties in selecting parameter values. The agreements of the simulation results are good for both models studied. However, taking into account the simplicities, facilities, efficiency and precise of the modeling, the multiple regression model is better and worth adopting. |
