摘要
Abstract
[Objective]Using a water environment numerical model to study the process of hydrodynamic and water quality changes in a seasonal ice-covered reservoir,revealing the variation patterns during the open water and ice-covered periods.[Method]In this paper,Xinlicheng Reservoir,a plain reservoir in the cold region of Northern China,was taken as the research object,and a three-dimensional hydrodynamic water quality model was built based on water environment hydrodynamics.The water temperature and TP concentration of a complete water period which include open water stage and ice-covered stage were simulated and analyzed,and the parameters of the model were calibrated and validated.[Result]The statistical analysis results show that the mean relative error(MRE)between the simulated and measured water level values of Xinlicheng Reservoir is 4.47％,and the water temperature MRE value was 12.5％.The MRE of TP concentration at all 3 sampling points are less than 20％.[Conclusion]The results can objectively reflect the changes in hydrodynamics force,water temperature and TP concentration of Xinlicheng Reservoir during the open water and ice covered periods,and can provide reliable reference and application value for the water environment management of Xinlicheng Reservoir.关键词
