| Abstract: | Based on the all-sand movable-bed model of dam area of Dadingzishan Hydroelectric Scheme, the changes of floor carrying capacity, flow velocity and pattem, flow condition for navigation as well as channel due to contracting the left branch in the 1 st Stage Project were tested. The effects of river bed deformation of the channel in case of various hydrological years and different engineering proposals for the left branch during the 1st Stage Projet were studied. And the measures to select the navigation line and to meet the requiremeat of navigation for the 1st Stage Project were proposed. |

| Keywords: | construction period of hydroelectric scheme bed deformation of river navigation condition |
