The Application of Historical Flood to the Identifying Cryptic Period of Flood Time Series
Zhu Ying-yuan · Journal of Catastrophology · 2004
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.
