本計畫之目標為開發一套有效率且準確的模擬系統，以了解灌溉渠道網路中之流體流動情形，並提供給決策與研究單位參考分析使用，以訂定更有效之水資源利用及農業灌溉策略。本計劃將以有限差分法為主要運算核心，進行空間與時間離散以開發準確的數值分析模式，求解一維de Saint-Venant方程式以了解各灌溉渠道中之流體運動情形，並利用結點連接關係將灌溉網路系統連結，以模擬準確的數值分析結果。本模式擬考慮數種可能發生之上下游邊界條件，以了解灌溉渠道網路中上游入流量與各渠道中流量之關聯性。除此之外，本計劃開發之模式也會考慮灌溉渠道中之不同水工結構物的影響。而在時間積分法的選擇方面，本計劃會同時開發隱式法與顯式法兩種不同的模式，並比較兩種模式之效能，並與現有國內外模式進行分析比較。 In this project, an efficient and accurate numerical model will be developed to simulate the flow fields of irrigation canal networks. The developed numerical model and numerical results can be provided to relevant projects for improving the managements of water resource and irrigation drainage systems. The finite difference method is adopted for spatial discretization of the de Saint-Venant equations. The relationships between the connected nodes will be used to form the simulation models for canal networks. In this study, different boundary conditions in upstream and downstream will be numerically examined. Besides, the influence of different hydraulic structures on the flow field will be systematically analyzed. The developed model will be compared with other models to verify the accuracy and efficiency of the developed model.
