Abstract: This paper reviews harnessing of the Lower Yellow River based on the characteristics of hyperconcentrated flows, including the tendency of water and sediment changes in the river, transport features of hyper-concentrated flows resistance properties laws of river processes, relationships between river channel geometries and incoming water and sediment, optimal composition of water and sediment to remodel the wide and shallow course of the Lower Yellow River, operation criteria to regulate water and sediment in reservoirs, harnessing measures, etc. when the harnessing is realized, the deposition in the Lower Yellow River can be descreased significantly, the water used for transporting sediment can be saved largely, the water resources can be utilized fully, and a new narrow, deep and stable channel will be formed.
