Influence Analysis of Yangxia Reservoir Construction on Hydrological Regime Based on One-Dimensional Hydrodynamic Model
Reservoir construction has a great influence on the hydrological regime of the downstream river channel.Based on the analysis of the influence of the initial impoundment of Yangxia Reservoir on the hydrological regime,the one-dimensional hydrodynamic model is used to predict the change of the hydrological regime of the reservoir area and the downstream river section during the operation period of Yangxia Reservoir.By selecting the dam site section of Yangxia Reservoir and the head section of Yangxia River as the prediction section,the influence of reservoir operation on the hydrological regime is calculated and analyzed by selecting parameters such as flow,water depth,flow velocity and water surface width,and the satisfaction degree of the ecological flow of the river section is analyzed.The results show that the discharge of the two predicted sections can meet the requirements of ecological flow control.The research results can provide technical basis for reservoir construction,regulation and operation.
