Abstract

In recent years Neyshabur’s plain has faced increasing slump in water table. Thus, the role of management and administrative factors is important. This article evaluates the effects of rainfall and climate on the fluctuations in GROUNDWATER LEVEL. We used 22 Pluviometry and Evapometry station data during 1352-1385. The average amount of rainfall and evaporation calculated with IDW method on Plain. According to man-Kendal, Valdvlfovitz and least squares tests was found the slope of GROUNDWATER LEVEL has negative trend and in 5 percent level is statistically significant. Therefore to find correlating rainfall on GROUNDWATER LEVELs trend of GROUNDWATER LEVEL measurement was omitted with and the difference curve and extrapolation method, at first. Results of correlation between rainfall and GROUNDWATER LEVEL showed that rainfall with a 10 monthly lag (R=0.539) has greatest impact in GROUNDWATER LEVEL. Besides, SPI index used for considering dryness and wetness effects on groundwater.SPI consecutive time series analysis showed long-term timescale of 42 monthly has greatest correlation with the GROUNDWATER LEVEL (R2=0.519). Also, analyzing seasonal GROUNDWATER LEVEL and SPI index in different delays and time steps pointed out that winter rainfalls with 30 monthly SPI and with four lagged seasons have the most effect on the surface of groundwater (R2=0.62).
