基于插补延长的俄日河径流分析

Runoff Analysis of E-ri River based on Interpolation and Extension Technology

径流是水电站径流调节和水能计算的基础。针对俄日河流域内水文站径流资料较短的情况,以邻近流域径流系列完整的水文站为参证站,通过分析两站同期月径流相关关系,将依据站径流系列插补延长,并对依据站延长后径流系列进行了代表性分析,得到水文站设计径流,为工程设计提供了依据。

Runoff data is the basis of runoff regulation and water energy calculation in hydropower stations. However, the runoff data measured by the hydrologic station in E-ri River basin is not long enough. Taking the hydrologic station with complete runoff data series in adjacent river basin as the reference station, the correlation between the monthly runoff data during the same period from these two stations is analyzed. Then, the original runoff data series are interpolated and extended. Representative analysis of the extended runoff series is carried out to get the design runoff data, which provides a necessary basis for the engineering design.
