| Abstract: |
| Effects roughness addition are calculated and regulation measure of maintenance and raise of water level at Yichang Station by river bottom protection and method and pool back-fill method in the reach from Yichang to Zhicheng of the Changjiang River compared by using a 2-D flow numerical simulation method. Calculation results show that each can meet demands. |
| Key words: river bottom protection and roughness addition pool back-fill water level reach from Yichang to Zhicheng of the Changjiang River numerical simulation |
