The dynamic programming model for water conveying and distribution system design is firstly presented in this thesis in the aspect of systematic optimization. taking the minimum earthwork or total cost as objectives, the longitudinal and transverse cross sections of two - stage and more canal system can be optimized to obtain optimal canal slops and relevant parameters, which will satisfy the restraints of water levels without erosion and sediment
在系統優化方面，本文在總結前人的基礎上首次提出了輸配水系統優化設計的動態規劃渠系協調優化模型，以土方量最小或總費用最小為目標函數，對兩級或兩級以上的渠系縱橫斷面進行優化設計，可得到滿足渠道不沖不淤、水位銜接及首末水位約束的最優縱坡及其相應的斷面參數。
