A model of using P+PR controller in Bival algorithm for open channel water distribution was developed.A comparison between simple upstream control and this control was done. The algorithm was verified by simulating the control process on computer. The analysis of the stability and steady going precision of the system indicates the feasibility of this algorithm.
