Hydrological Calculation and Analysis of Water Supply Engineering for Ecological Immigrant Poverty Alleviation and Development in Central Gansu Province
In order to improve the efficiency of agricultural irrigation,consolidate the achievements of poverty alleviation in the region,and provide water resources guarantee,the construction of water supply project for ecological migration poverty alleviation and development in central Gansu was carried out.To meet the needs of engineering planning and design,hydrological and hydraulic calculations were carried out on the design section of the Yellow River main stream.By compiling the layout and hydrological basic data of the main stream of the Yellow River and its channels along the line,and combining with the historical results of large-scale engineering design in the basin,the Anningdu Hydrological Station and Lanzhou Hydrological Station were selected as the main reference stations.Considering the joint operation mode of Longyangxia and Liujiaxia reservoirs and the characteristics of regional runoff and concentration,the results of the main stream and channel runoff,flood,and sediment were obtained through interpolation,extension,reduction calculation,and empirical formulas for power generation engineering.These provided technical basis for engineering planning and design.
