Abstract

In this article, with the aid of BIVARIATE TIME SERIES as CROSS CORRELATION FUNCTION and cross spectral function, ZONATION of Shahr-e-Kord aquifer was accomplished. To prepare this ZONATION, the monthly time series of water tabel fluctuations of 17 pizometers have been used. According to the ground water flow direction, the total correlation of time series of the chosen pizometers was calculated by CROSS CORRELATION FUNCTION. Using single spectral density, the fluctuations in time series were determined.According to the results, trend component, seasonal fluctuations with frequency of 0.083 and cyclic fluctuations with return period of 4.5 years were identified. After removing trend component, it was observed that the main remaining fluctuations in time series were seasonal fluctuations. To make a precise assessment, cross spectral analytical methods have been used, and the amount of correlation and lag time of the two series of frequency of 0.083 (sesonal fluctuations) have been examined.Finally, according to the results of CROSS CORRELATION FUNCTION and cross spectral density, the region was divided into four zones: zone 1 including high correlation- low phase lag, zone 2 including high correlation-high phase lag, zone 3 including high correlation-medium phase lag and zone 4 including low correlation- high phase lag.
