Abstract :
Lack of hydrological data in arid regions is often a huge hurdle water resources investigation. This paper discusses and investigates the long-term rainfall trend by using a nonlinear time series analyses method (Fourier/wavelet and Power Spectrum Analysis) as an alternative way for future research on the prediction of hydrological data.
