| Abstract: | Curving cut-off is a project measure of channel management in mountainous river.Not only flood control capability of the upper beach can be improved with curving cut-off project,but flood risk of the downstream beach can be aggravated.Taking the Yong'an River in Zhejiang province as an example in this paper,influence on flood control by curving cut-off in mountainous channels is analyzed.Results show that the main influenced factors are the storage of retarding flood and flood flow velocity.The analyzed met... |
