This paper presents a systematic study of constant-volume control for transient flow in open channels. A mathematical model of optimal constant-volume control has been established based on St Venant equations and modern control theory. A computational program has been made. Both numerical simulation and model test have been carried out for a model Channel with three reaches and four gates and good agreement has been achieved. The conclusion is that the mathematical model presented in this paper can be used in the design of fully automatic programed-control in open channels.
