Brief introduction of Dongzhuang Reservoir

The reservoir hub is located in Dongzhuang Township, Liquan County, xianyang City, Shaanxi Province, at the end of the canyon in the lower reaches of Jinghe River, a secondary tributary of the Yellow River, about 80 kilometers away from Xianyang City, about 100 kilometers away from Xi City, and about 30 kilometers away from the head of Jinghe Canal in the lower reaches of Jinghe River. Initially, the maximum dam height is 228m, the total storage capacity is 2.987 billion cubic meters, the flood control storage capacity is 420 million cubic meters, and the storage capacity for sand retention and water diversion is 2.02 billion cubic meters. The total static investment of the project is 9.302 billion yuan. The total construction period is 7 years, 1 1 month. After the completion of the reservoir, it will effectively relieve the flood control pressure in the lower reaches of Weihe River when Jinghe River and Weihe River flood at the same time, and reduce the sedimentation in the lower reaches of Weihe River. Reservoirs can adjust water and sediment, create artificial flood peaks, increase scouring opportunities in the lower reaches of Weihe River, reduce Tongguan elevation, gradually restore the functions of the lower reaches of Weihe River, and reduce flood disasters.
