Abstract:

Water resource has become a bottleneck for the social and economic development of Guanzhong region of Shaanxi province. A model of unit optimal allocation of water resources in Shaanxi’s South-to-North water transfer project is set up, and the model is solved by using Genetic Algorithms (GA). The unit water resources optimization allocation system is established. Comparison between the results of optimal allocation and conventional allocation showed that, on the premises of guaranteeing water supply, the optimal system can reduce the total water shortage by 98.75 million cubic meters. This research provides reference for the reasonable water allocation in this region and the determination of water transfer quantity for the water diversion project from Hanjiang river to Weihe river.

Key words: unit optimal allocation, water resources, Guanzhong region of Shaanxi province
