Objectives
The Yellow River has become the most complex and difficult river in the world because of "less water and more sand, different sources of water and sand, and the uncoordinated relationship between water and sand". The lower reaches of the Yellow River is a "wandering type" river, because of the long siltation, it has become a world-famous "hanging river". The traditional sediment control scheme of "blocking, discharging, releasing, adjusting and digging" is limited in the management of the beach area due to various reasons. Innovative introduction of "sand guide" device, with lower investment, to achieve better beach management results.
Conclusions
In addition to the Yellow River, the technology can be used in other rivers and reservoirs of
similar kind. The flood discharge capacity will be improved in the river with severe sedimentation. In the main stream and tributaries of the reservoir with serious sedimentation, the reservoir capacity can be better restored, so as to improve the comprehensive benefit of the reservoir.
