Preliminary analysis of flow and sediment variation mode of the Yangtze river

For the rich water and sediment resources, the Yangtze river is of great importance in sustainable development of Chinese economy and society. According to collected and processed hydrologic data of main hydrologic stations for nearly 50 years, the flow and sediment variation process, characteristics and tendency of the Yangtze river are introduced, and the variation law and mode of flow and sediment of the Yangtze river in near years are analyzed. The analysis results demonstrate that the flow and sediment variation of the Yangtze river has some regularity and correlative research should be strengthened.
