| Abstract: | To solve the problem of backwater at Sangyuan G orge and flood prevention in Lanzhou section of the Yellow River,the cause,chara cteristics,height and range of backwater and other related factors are analyzed .The effect and range of backwater at Sangyuan Gorge in different discharges are determined.Model experiments and value calculations are carried out.The results are well coincided with actual data of the protype section of the river.It show s that the model design is reasonable and the calculation method is reliable.It can accurately infer the variations of the backwater curve with discharge and ti me. |
