Abstract: Regarding Xinchang-Jianli reach of the Middle Changjiang Jingjiang River as an example, on the basis of field data of runoffs, sediment loads and morphologies of river channels, deposition-erosion amounts of Xinchang-Jianli reach from Jun.1987 to May 1991 are estimated by sediment budget method and morphological change method. Difference, suitability and key influential parameters or coefficients of these two methods are preliminarily contrasted and analyzed. Main conclusions are as follow: (1) By means of sediment budget method and under separated sand size 0.0625mm of wash load and bed material load, the deposition amount of XinChang-JianLi reach from 1st Jun. 1987 to 31st May 1991 is estimated at 0.4314×10 8 t, while by means of morphological change method and under bankfull stage of 34.0 m, the deposition amount of XinChang-JianLi reach from May-Jun.1987 to May 1991 is estimated at 0.438 3×10 8 t., and two estimates are very close. (2) The key parameters or coefficients influencing sediment budget method are the separated sand size of wash load and bed material load and the suspended sediment grading curves, while those affecting morphological change method are the bankfull stage and the sediment dry density. (3) Under quasi-equilibrium of deposition-erosion and conditions of channel-forming, once the separated sand size of wash load and bed material load (for sediment budget method) and the bankfull stage (for morphological change method) are properly selected, deposition-erosion amounts estimated by both Methods can be obtained identical or very close, the more deviation from deposition-erosion equilibrium and channel-forming condition, the more different of results of these two methods.
