【Abstract】 in this paper the method of optimum hydraulic design for improvment of canal system is studied, and an optimal model combining the simulation optimization with expert appreciation has been proposed. In the model the minimum project improvement costs and the rationality of structure and construction are regarded as the appraisable object. According to the physical relations in the simulation model and the operational regulations,which are defined by this paper, the optimum hydraulic parameters of the canal system can be obtained through simulation program running.更多还原
