•A mathematical model considering the operation of 24 mega reservoirs was proposed.•The sedimentation mainly occurs in the mainstream during the flood season.•The cascade reservoirs operation leads to easier and prolonged sedimentation. The intensive construction of large dams in the upper Yangtze R...
