Influence of hydrodynamics on formation of braided fluvial delta
The changes of hydrodynamics will influence the formation of braided river delta.Based on many previous studies, this article does some quantitative analysis of migration rate of channel, sedimentation position for sandbody and the shape of bar under the conditions of flood, common water and low water on the basis of sedimentary simulation techniques, and transportation model of sandbody is set up under the experimental condition.The results of flume experiment show that the difference exists in the position of the thickest sandbody under diffident hydrodynamic conditions.Migration rate of channel is the highest in common water period, followed by flood period and low water period.The ratio of sandbody width/height increases and the ratio of length/width decrease gradually from flood period to common water period to low water period.
