Sustainable Water Dispatching for the Lower Reaches of the Yellow River in Non-flood Seasons.

Due to the water resource shortage in the lower reaches of the Yellow River in recent years, this paper presents a study on water dispatching. From the view of temporal and spatial allocation of water resources) water dispatching consists of two components: reservoir regulation and water dispatching for reaches in order to implement the total volume control and coordination between users. The combined regulation model of Sanmenxia reservoir and Xiaolangdi reservoir giving full consideration to the priorities of user's water demands, conforms to the reality of the Yellow River The water-dispatching model for reaches applies various methods including the equal proportion method, weighting method, and user-involving method, which are characteristic of simplification, flexibility, and practice. In addition, the influence of flow routine time has also been considered to enable the water-dispatching scenarios obtained to be more practical The methods and models have been applied in the praxis of water dispatching in the lower reaches of Yellow River in 2000 and have resulted in significant economic and social benefits.
