The Yellow River: Managing the Unmanageable
Hydrosolidarity in the Yellow River is a complex and difficult task, especially as this river has sediment problems that are unique in the world. The balancing of discharge needed for sediment management, relative to that needed for augmentation of water supply within and outside the basin, and for conservation of threatened ecosystems downstream presents a series of compromises that must rank as amongst the most challenging in basin-wide management of major world rivers. Until such time as south-to-north diversions are in place, the Yellow River is the only major water supply to the North China Plain, where water scarcity is now estimated to be some 40 km3 annually, representing 70 percent of the flow of the Yellow River. The hydrological management of Yellow River erosion involves three major factors: erosion and sediment transport, flooding, and river desiccation in the downstream reaches. This paper outlines several major development projects in the Yellow River basin that are attempting to achieve hydrosolidarity while, at the same time, providing needed water supplies to water-scarce parts of the basin.
