Modeling, Simulation and Automatic Control of Long Distance Water Transfer in Winter

In order to automatically control the long distance water transfer in winter, mathematic models, modes of water transfer in winter, operation methods and control models of long distance canal system are introduced. After receiving the cold current forecast, the discharges must be reduced so as to decrease the flow velocity. When the flow velocities are all below 0.4m/s, ice flowers will accumulate and form ice cover. Then the canal system successfully achieves transition from normal open flow state to icing model state. This paper points the present research process and the further research issues.
