Abstract

The operation of Three Gorges project has raised the water stage in its reservoir and caused sedimentation. In this study the sedimentation place and volume in navigation channels of the fluctuating backwater area was calculated. A non-interpolation method of DEM generation was successfully designed for this purpose. The results revealed that: After 2006 nearly all important navigation section has been affected due to the raise of water stage, but only the `tunaozi´ section´s navigation may be severely impeded since most sedimentation did not deposit in the main channel in other sections.
