The construction and operation of large hydropower projects will change the runoff spatial and temporal distribution,especially the consistency of measured runoff and flood data at the downstream hydrological station. Taking Maotouma Hydrological Station in the middle reaches of Dadu River as an example,we analyzed the consistency of the measured runoff and flood data from 1987 to 2014 and converted it to natural condition by water balance method after the operation of Pubugou Hydropower Station. The results show that the converted runoff and natural data are consistent with the nature and can be used in engineering design.
