河滩地整治工程对颍河阜阳闸水文站影响分析

Analysis of the Influence of Flood Land Regulation Project on Yinghe Fuyang Hydrological Station

为提高城市河流堤防防洪标准,修复改善河滩地水生态环境,对颍河阜阳闸水文站管理范围内的左岸滩地进行整治,根据水文监测断面流速、含沙量分布规律和河流特性分析以及工程施工河流的冲刷壅水计算结果,河滩地整治工程对水文站的监测环境、闸上水位、断面流量、沙量和水质监测均有一定的影响,据此提出了相应的水文监测补救措施和建议,以保证水文站资料的连续性以及防汛工作的正常开展。

In order to improve the flood control standard of urban river embankment,repair and improve the ecological environment of the flood land,the left flood land within the management scope of Yinghe Fuyang Hydrological Station is regulated. Through the analysis of the flow velocity of the hydrological monitoring section,the distribution law of sediment concentration and the characteristics of the river as well as the calculation results of the erosion backwater of the river in the project construction,it can be concluded that the flood land regulation project has certain influence on the monitoring environment of hydrological station and the monitoring of upper water level of sluice gate,section discharge,sediment quantity and water quality. Accordingly,the corresponding remedial measures and suggestions for hydrological monitoring are put forward,which can ensure the continuity of hydrological station data and the normal development of flood control work.
