Utilization and Management of Sediment Resources in the Yangtze River Basin
Publication: World Environmental and Water Resources Congress 2020: Water Resources Planning and Management and Irrigation and Drainage
ABSTRACT
The Yangtze River Basin has a huge amount of sediment transport and plays an important strategic role in China’s social and economic development. In recent years, the time-space distribution of the sediment in the Yangtze River Basin and the process of production and transportation have changed greatly. The contradiction between supply and demand of the sediment resources is becoming more and more serious. This paper summarizes the main ways of utilization of sediment resources in the Yangtze River Basin, and analyzes the new situation of sediment transport and sediment redistribution in the Yangtze River Basin. In order to alleviate the contradiction between sediment supply and demand in the Yangtze River, it is necessary to strengthen the combined water and sediment operation in the upper reaches of the Yangtze River to optimize the allocation of water and sediment resources, improve the uneven distribution of sediment from a macro level, and carry out sand excavation and silting in the upstream reservoirs to make full use of the sediment resources of the reservoir. We should strengthen the management and planning of sand mining in river courses, make rational use of sediment resources in tributaries and lakes, reduce the pressure of sediment demand in the main stream of the Yangtze River, and actively promote the comprehensive utilization of dredged sand in the channel of the Yangtze River.
