| Abstract: | According to the measured data in fluctuating backwater region of the Three Gorges reservoir,the sediment transport and the scouring and deposition characteristics under the normal storage water level 175 m condition were primarily analyzed in this paper.The inherent mechanism of channel adjustment was revealed,then the changes of water and sediment condition and the regularity of scouring and deposition in this reach were summarized.The results can provide scientific basis for future navigation channel regulation and sediment transport research. |
