The time dynamics of gravity signal measured in Sheki, a site in Azerbaijan, where mainly crust deformation processes are present, is investigated by using the power spectrum method and the multifractal detrended fluctuation analysis. Our findings point out to the presence of two main...

Scaling behaviors in monthly streamflow and Standardized Streamflow Index (SSI) of 11 gauging stations in Ebro basin (Spain) were analyzed: four located in the mainstream and seven in tributaries. The time span is from 1950 to 2005. The methods used are the power spectrum and the detrended...

The characterization of 1/fα scaling behaviour in normalized difference vegetation index (NDVI) satellite data of forest ecosystems in southern Italy has been performed using the multiple segmenting method (MSM) and detrended fluctuation analysis (DFA). Our findings point out to the...

The time dynamics of tidal fluctuations measured in three sites in Bahia Blanca Estuary (central Argentina), Ingeniero White, Puerto Belgrano and Torre Mareografica, are analyzed. To investigate the time series of the tidal waves we used two different approaches: the power spectral density (PSD)...
