Hilbert-Huang Transform Analysis of Hydrological and Environmental Time Series

The Hilbert-Huang Transform ((HHT) is a recently developed technique which is used to analyze nonstationary data. Hydrologic and environmental series are, in the main, analyzed by using techniques which were developed for stationary data. This has led to problems of interpretation of the results. Environmental and hydrologic series are quite often nonstationary. The basic objective of the material discussed in this book is to analyze these data by using methods based on the Hilbert-Huang transform. These results are compared to the results from the traditional methods such as those based on Fourier transform and other classical statistical tests.Ramachandra, A. is the author of 'Hilbert-Huang Transform Analysis of Hydrological and Environmental Time Series', published 2008 under ISBN 9781402064531 and ISBN 1402064535.
