The analysis on reservoir sediment deposition and downstream river channel scouring after impoundment

Lu Jinyou,Huang Yue,Wang Jun

Strategic Study of CAE 2011, Volume 13, Issue 7,   Pages 129-136

Abstract: after impoundment and operation of the Three Gorges Reservoir, the reservoir sediment deposition and downstreamriver channel scouring are described briefly and compared with the research results achieved in theIt is indicated through analysis that the reservoir sediment deposition and downstream river channelscouring during 8-year impoundment and operation are still within the original forecast, so the original

Experimental study on flow behavior at open channel confluences

WANG Xiekang, WANG Xianye, LU Weizhen, LIU Tonghuan

Frontiers of Structural and Civil Engineering 2007, Volume 1, Issue 2,   Pages 211-216 doi: 10.1007/s11709-007-0025-z

Abstract: confluences becomes very complex because of the interaction between the tributary and the main river.confluence flow may be divided into several zones including a zone of separation immediately downstreamof the junction branch channel, the maximum and minimum velocity regions at the upstream and downstreamin the confluent channel, and a shear plane developed between the two combining flows downstream ofthe confluent channel.

Diverting Seawater to Scour the Estuary and to Regulate the Lower Yellow River

Lin Bingnan,Zhou Jianjun,Zhang Ren

Strategic Study of CAE 2000, Volume 2, Issue 4,   Pages 25-33

Abstract: This flow of “clear” seawater would strongly scour the channel downstream of Lijin and reduceThus a total of about 380 km of river channel would be scoured down.The reach downstream of Lij in would be transformed from an above - the - ground river to a down - in- the - ground river and the reach above Lijin would possess a deeper main channel.afterwards by scouring with seawater.
