| Abstract: | According to channel topographic and water sediment data, using methods of cross section survey and sediment balance, the changes and distribution law of channel scouring and silting in midstream and downstream reaches of Changjiang River are systematically studied in this paper. The results improve that main channel was scoured and flood plain and river branch were silted. And the strong capability of channel self adjusting in Mid and Down stream reaches of Changjiang River is analyzed and proved. |
