Abstract
Water resources optimal regulation is an important means to mitigate the shortage of water resources and promote social and economic sustainable development in regions or watershed. With the rapid development of urban population and industrial and agricultural production in recent years, the shortage of water is becoming more and more serious in Jiaodong area. The four regions with serious water shortage including Weifang, Qingdao, Yantai and Weihai in Jiaodong area are the typical research areas. In combination with the water transfer project of Yellow river to Qingdao and the south-to-north water transfer project, the water diversion is carried out to alleviate the contradiction between water supply and demand of Jiaodong area. The year of 2014 deemed as the base year and the years of 2020 and 2025 are the planning years. Based on the supply and demand analysis of water resources, an optimal regulation model is built with the minimum total water shortage considering the constraints of water supply capacity of project, water distribution capacity and minimum water supply of bleeds and so on. The optimal regulation schemes are obtained by solution model using MATLAB programming. The results show that water shortage rate of the four cities decreases significantly in annual regulation. For different planning years, guarantee rate of 50%, 75% and 95%,the total water shortage rate will be reduced by 15.35%、15.75% and 16.85% respectively in 2020, and in 2025the total water shortage rate will be reduced by 13.27%、13.26% and 14.19% respectively. Therefore the water resources optimal regulation of inter-basin water transfer project can effectively mitigate water scarcity and the contradiction between water supply and demand in Jiaodong area.

Optimal regulation of water resources is an important means to relieve water shortage and promote sustainable development of social economy
Water transfer across river basins is one of the important means to solve the problem of water shortage in the area。
After the founding of the People's Republic of China, China successively built a number of water diversion projects, such as the Guangdong Dongshen Water Diversion Project, Water Diversion Project from Luanhe River to Tianjin, Water Diversion Project fromYellow Rive to Qingdao, and the South-to-North Water Diversion Project
Summary
Optimal regulation of water resources is an important means to relieve water shortage and promote sustainable development of social economy. Water transfer across river basins is one of the important means to solve the problem of water shortage in the area。. In order to realize the optimal scheduling of water resources across river basin, different optimization scheduling methods are needed. Optimization methods include linear programming[1,2] , nonlinear programming[3] , dynamic programming [4] , stochastic programming [5], multi-objective programming [6,7] and so on. This paper takes the Jiaodong water transfer project as the research object. Under the existing engineering conditions, according to different water inflow conditions, the linear programming method is used to optimize the scheduling of the Yellow River water and the Yangtze River water to provide decision support for operation management
