This paper carried out the model experiment for Xinjiang KZAWT water division project which was planned to reinforce and consolidate under working conditions of various frequency of flood in the watercourse.The result shows that the greatest split ratio of KZAWT pivot is about 40% and far smaller than 70% proposed by origintal design program.Under all levels of flow, the headrace channel meets the need of design flow.The discharging capacity of floodgate and spillover side weir is greater than the requirement of design and satisfies the requirement of discharge. The dam break will take place when the practical inflow is less than the checking flood flow of 3 148 m3/s. The result of sediment transport experiment shows that it is effective to avoid the sediment going into the division canal through appropriately adjusting the flood-discharging and sand-sluicing gate.The research results can provide evidence and guidance for the reinforcement design of KZAWT pivot and give reference to the reinforcement design of similar projects which have more flood-division buildings and face complicated discharging conditions.
