Abstract

The aim of the present study is to monitor the drop of GROUNDWATER level in the SAVEH AQUIFER. To achieve this goal, monthly precipitation from five weather stations, monthly flow in three gauging station, monthly volume of discharges and water table data in 63 wells were investigated. The results of assessing meteorological drought using Standardized Precipitation Index (SPI) in two stations (Imamabad and Ahmadabad) indicate that extreme drought has occurred in 1980, 1983 and 1985. The results of correlation coefficient between the Standardized Precipitation Index (with scales 1, 3, 6, 9, 12, 18, 24 and 48 months) and water table data (with LAG TIME 1, 2, 3, 4, 5, 6, 12 and 24 months) indicate high compliancy, SPI with scale of 24 and 48 months and GROUNDWATER level with time delay of 5 months (0.806 and 0.762) respectively for two Station of Ahmadabad and Imamabad. Review of rainfall and surface flow data at Shah Abbasi, Razin and Jalayer show increasing decreasing trends in rainfall and flow, respectively. According to results of this study construction of Saveh dam on Qarechay River in 1994 is the main reason for drop of GROUNDWATER level in SAVEH AQUIFER.
