| 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. |
