Abstract: Analyzed the sediment-transport process in the Lower Yellow river, the concept and normal calculating method for sediment-transport water volume are proposed. Based on field data of sediment and water volume in the Lower Yellow River from 1950 to 2000, the sediment-transport water volume and unit sediment-transport water volume in LYR are calculated. Furthermore, BP model is set up to calculate the high efficient sediment-transport water volume in the Lower Yellow River. Compared the results of BP model with normal calculating method, BP model is confirmed for calculating the high efficient sediment-transport water volume in the Lower Yellow river.

Authors: Jun Yan, Biao Liang, Hui Cao, Yu Hua Zhang

Abstract: Analyzed the sediment-transport process in high sediment-laden river, the new concept and calculating method for sediment-transport water volume are proposed. Based on field data of sediment and water volume in the Lower Yellow River from 1950 to 2000, the sediment-transport water volume and unit sediment-transport water volume in LYR are calculated. Meanwhile, relations between them and influencing factors are confirmed to calculate efficient sediment-transport water volume after construction of the Xiaolangdi reservoir.
