Abstract: There are probably many kinds of complicated geological condition and also big different geographic environment and weather condition along the transbasin diversion open channel project. In order to control the damages caused by the sudden events including natural disasters, traffic accidents or other reasons, some corresponding emergency water transfer dispatch measures should be taken, the water flow should be required to be cut or water discharge should be substantially changed in a very short period. the effective emergency water transfer dispatch can guarantee the safe, stable and constant water transfer running of the project. Combining the actual situation of the project's layout and operational dispatch, this article focuses on categorizing the sudden events which probably happen in the normal water supply process of the transbasin diversion open channel project and put forward relevant sluice gates emergency water transfer dispatch measures according to four aspects which are the safety of the water quality, the safety of the open channel and the hydraulic structure, the fault of the equipment and the safety of the society. With the constrained conditions and the thoughtway in this article, the emergency plan of the water transfer dispatch is also included. The transbasin diversion open channel project transfers water flow automatically during the whole route, without any reservoir but with a lot of check gates, bifurcation gates and receding gates. To guarantee this complicated system being operated safely and reliably, the water transfer dispatch must be very difficult and complicated without saying the difficulty and the complexity of the emergency water transfer dispatch on very emergency conditions. A database of the emergency plans of water transfer dispatch for typical events is suggested to be worked out.
