历史洪水在洪水序列隐含周期分析中的应用

The Application of Historical Flood to the Identifying Cryptic Period of Flood Time Series

历史洪水调查是洪水序列的重要组成部分,对揭示洪水序列的周期,论证周期的稳定性和可靠性具有重要的作用。本文提出具有历史洪水调查的不连序序列三种周期分析模型,理论分析和实例计算结果表明,文中提出的模型是合理和可行的。

Historical flood investigation, being an important part of flood, involves some properties of flood time series. Thus it is very important and useful for historical flood investigation to reveal the flood periods and ascertain the stability and reliability of the period. In this paper three improved periodic analysis models which can be used to identify incomplete flood time series with cataclysm and/or lacunae are presented. Theoretical analysis and calculated results show that the models are available and reasonable.
