Abstract: Analyzing the sediment-carrying mechanism and the real process of sediment-transport in the river channel, a new concept and calculating method of sediment-carrying water volume have been put forward. According to the field data from 1950 to 2000, the sediment-carrying water volume and unit sediment-carrying water volume in the lower Yellow River have been calculated, meanwhile, the relation between them and their influence factors have been confirmed to calculate the efficient sediment-carrying water volume after the construction of Xiaolangdi reservoir on the lower Yellow River. A sediment mathematic model has been used to calculate and verify this volume.
