The reach is located at the junction of the first and second steps in China, with more water and less sand, and the advantages of high-level water supply are obvious. It plays a strategic role in the regulation of water, sediment and electricity in the Yellow River and is a valuable resource for the effective allocation of water resources in time and space.
