Abstract

Appropriate modeling of RAINFALL is one of the most important tools in different parts of water resources management such as watershed, flood control and water shortage crisis. Statistical and conceptual models can't predict the RAINFALL accurately, because of nonlinear relations and variable characteristics in space and time of the hydrological cycle. On the other hand hydrological TIME SERIES modeling is difficult because they are affected by complex factors and aren't distributed in space and time equally and usually isn’t stable. Many new methods and models are available for analyzing and simulating hydrological TIME SERIES. In recent years, there has been an increasing interest in the use of wavelet analysis in a wide range of fields in science and engineering.In this paper, we use Meyer WAVELET THEORY to forecast monthly RAINFALL in SAADAT-SHAHR and ARSANJAN and then the results are compared with TIME SERIES of SARIMA and Box-Jenkins results. We use Box and Cox transformations for data normalizing in TIME SERIES. Comparing of correlation coefficients in these methods showed wavelet has more accurate predictions than TIME SERIES and SARIMA also offers more accurate results than Box-Jenkins.
