Influence of Floodplain Flooding on Channel Siltation Adjustment under the Effect of Vegetation on a Meandering Riverine Beach

Flooding in a sediment-laden floodplain is affected by riverine beach vegetation and the shape of meandering compound channel. The laws water sediment exchange deposition distribution troughs are very complex. These factors play significant role formation development secondary suspended rivers, adjustment horizontal gradient, even evolution flood control situation. In this study, we used combination experimental simulation theoretical research to carry out generalized model test flooding evolution, analyzed lateral characteristics flow channel under conditions vegetation, revealed pros cons on siltation. results with showed that main stream was not only concentrated but also appeared near foot left right bank levees formed discharges along embankment. As siltation mainly at lip, had effect slowing down velocity. Whether it row or full both sides bank, played an important stability When there no beach, easy move. arrangement uniform velocity which reduced phenomenon excessive increased will provide basis for utilization areas river management lower Yellow River have great significance enriching basic theory movement promoting integration hydraulics, dynamics, ecology.
