摘要
Abstract
Based the theoretical foundations of fluvial process, the mechanism of backwater deposits extended upstream of Sanmenxia Reservoir in Weihe River has been analyzed. Sedimentation in forward period decreased the Tongguan reach flow velocity with the same discharge, decreased the main channel width and the flood conveying capacity in lower Weihe River. So that the power for keep the fluvial equilibrium has been decreased. It is the fundamental reason that created the backwater deposits extended upstream and serious sedimentation in channel occurred.
The bed load of branch stream into the Weihe River increased the backwater deposits extended upstream.关键词
