Real-time water2ssupply optimal operation in Li River Basin

Cho osing the thir d2phase w ater2tr ansfer pr oject as the research object, w e studied the r eal2time w ater2tr ansfer o ptimal operatio n in Li River Basin. First ly , w e built the quantitative r esponse relationship betw een the release of the w ater2supply res2 er voirs and w ater demand of the contr ol sect ion based on Musking umcs f low a lg orithm. Then we pr oposed a real2t ime w ater2 transfer optimal o per atio n model and co rr esponding operating rules fo r the r eser vo irs gr oup o n Li River, w hich to ok into co nsid2 er ation the water flow evo lutio n delay and the ecolo g ical water demand. T hr ough co nstr aint2handling t echniques, w e tr ansfo rmed the model into a question which could be so lved by linear programming. The application results showed that the joint operation of the six reservoirs on Li River ( including Fuzikou, Chuanjiang , Xiaorong jiang, Qingshitan, Wulix ia and Sicanjiang reservoirs) could raise the wa2 ter2supply daily assurance rate to abo ve 94% in especially dr y years. This study has important significance fo r maintaining a healthy riv er channel, increasing navigation assurance rate, and impro ving eco nomic benefits of to urism on Li River.
