Sedimentation in Yangtze River above Three Gorges Project since 2003
摘要
Abstract
Analysis based on field data of the Three Gorges Project ( TGP) since 2003 shows that sedimentation in the Yangtze River above the TGP mainly deposited in the permanent backwater region. However, in the permanent backwater region the sedimentation did not spread widely and continuously. Totally, there are mainly three kinds of deposition section form. Sedimentation in the Yangtze River above the TGP has a close relationship with the plan form of the channel, the average water depth and the average cross-sectional velocity. The empirical relationship between the average water depth and the average velocity when sedimentation happening is obtained by statistic analysis finally.关键词
