Water Resources Optimal Allocation Of The Water Imported Areas In The Hanjiang-To-Weihe River Water Transfer Project

Water resources shortage has become one of the key factors that restrict the development of many of our cities, industries and agriculture. The Weihe basin in Shannxi is an arid and semi-arid Area which is shortage of water resources; the limited water resource can not meet the development of the social economy, so Inter-basin Water Transfers is the urgent affair of solving the problem of water resources shortage and improve the water environment. Hanjiang-to-Weihe River Water Transfer Project just the way to solve the present water shortage of Guanzhong. How to make the water resources system rational operation, scientific adjustment is a problem that needed solve urgently, so this study is very significant.By reviewing the current researches on this field both at home and abroad, the dissertation makes a detailed and systematic study on the water resources optimal allocation of the water imported areas in the Hanjiang-to-Weihe River water transfer project. After researching the present water supply situation, the author predicted the water demand in imported areas with the BP Artificial Neural network and classification of water quota. After one and twice analysis of supply and demand balance of water resources in imported areas the quantity of the transfer water resource was put forward with the guidance of sustainable development. Based on the system analysis method, the large-scale system decomposition and coordination model of imported area water resources was set up, through it optimally allocating the water from Hanjiang. The main achievements are as follow:1) Predicted the water demanded in Guanzhong imported areas with the BP Artificial Neural network model and optimized it with genetic and simulated annealing algorithms.2) Based on the system analysis method and considerations of the area's economic, social and environmental factors, the large-scale system decomposition and coordination model of imported areas water resources was set up, through it optimally allocating the water in imported areas. This research will help the project fulfill its scheduled object and acquire biggest efficiency.
