Study On The Optimal Allocation Of Water Resources In Tao River Diversion Project Water Suppiy Arca In Gansu Province

Tao River Diversion project take Tao River as its water supply resources, which is a main tributary river of the Yellow River in Gansu province. It is a large-scale interbasin water transfer project solving the water shortage problem in arid zone of the middle area in Gansu province.
