摘要
分析了下关站潮位过程的影响因子,提出了潮位过程的平均潮位、潮差、潮位过程平移、潮位过程分解与重建等概念,并用简单实用的统计相关方法建立了下关站潮位过程预报模型;用水文观测资料对所建立的模型进行了率定,率定结果表明,所建立的模型具有一定的预报精度、能够满足秦淮河流域水动力学洪水预报模型的边界条件预报要求。
The paper analyses the influence factor of tidal level process in Xiaguan, puts forward some concepts of average tidal level, tidal difference, translation of tidal level process, decomposition and reconstruction of tidal level process, sets up the forecast model of tidal level process in Xiaguan station with statistical method, calibrates the forecast model with hydrological observation data, the calibration indicates that the forecast model has the forecast precision, satisfies the forecast demand of boundary condition for hydrodynamic flood forecast model in Qinguaihe fiver basin.
