Abstract

Taking a typical reach of the Yellow River as the research object, using decomposition, coordination, coupling and control technology and through real-time data transmission and feedback, the simultaneous coupling of water quantity and quality is realized. Based on the identification parameters of water intake, section discharge and water quality index in the water function areas, the on-line identification and process control of the allocation target are realized, and an integrated model of water quantity and quality with the functions of cycle iteration, on-line feedback and rolling correction is established. Taking the natural runoff from 1956 to 2000 as input and the water demand and sewage discharge from the upper reaches of the Yellow River in 2015 as an example and through optimization, an integrated water quantity and quality allocation scheme for the typical reach of the Yellow River was put forward. It is shown that the model could realize the integrated allocation of water quantity and quality in the Yellow River.
