Danjiangkou Water Conservancy Project located in the lower reaches of the Hanjiang River and the confluence of water of 800 meters, is 20 in the 1960s China’s most spectacular projects, the Han River is the largest water control project, by retaining buildings, power structures, navigation structure, diversion structures and other components.
Danjiangkou Water Conservancy
The water retaining structures 2.5 km chief of the dam, the largest dam height of 97 m, crest elevation 162 meters, the contents six generating units with an installed capacity of 900,000 kilowatts, the average capacity of 3.83 billion.
The project area of 95,200 square kilometers control basin, the total drainage area of 60%, with flood control, power generation, irrigation, shipping and aquaculture, and other comprehensive efficiency. Since the completion of the Danjiangkou water hub, the total flow of 1,000 cubic meters to retain peak / s floods more than 67 times, reduce downstream submerged 541 million mu of cultivated land, flood control benefits estimated 26.24 billion yuan, protection of the middle and lower reaches of the Hanjiang River flood control safety.
Danjiangkou Project is not only radical River, the key to the development of the Han River project, but also the best of the South-North Water Transfer Project water. September 26, 2005, South North Water Transfer Project water – water conservancy hub Danjiangkou dam project officially started construction. Danjiangkou Reservoir as a source of the center line water diversion project built by the late End scale, the top of the dam height will be increased to 175 meters, the normal water level from 157 meters up to 170 meters, and the corresponding increase in storage capacity can be 11.6 billion cubic meters, the recent annual water diversion 9500000000 cubic meters, up diverting water from the late 13 billion cubic meters.
