Investigation. Design calculation manual is divided into five chapters. The first chapter, introduction. The second chapter, the design basis and norms. The third chapter, the basic design data. The fourth chapter, the irrigation system and the heavenly stems and Earthly Branches flow calculation. The fifth chapter, the design of tunnels. Lijiaxia reservoir irrigation area is located in the territory of Qinghai Province, Longhua Hui Autonomous County and Jianzha County, geographic coordinates between east longitude 101 ° 48 - 102 ° 05, north latitude 36 ° 07 - 35 ° 50, as the the Yellow River River Valley terrace and part of the North-South cross-strait mountain slope. Irrigation projects in Lijiaxia reservoir, is the use of raising water level Lijiaxia reservoir and the Yellow River is rich in water resources, agricultural irrigation water from the dam reserved holes, provide water for agricultural irrigation area on both sides of the Yellow River, promote the adjustment of planting structure, a farmer to take off deficient to become rich go straight towards well-off, improve the ecological
