Abstract

The aim of this study was to review the effect of EXCESSIVE WITHDRAWALs and recent DROUGHTs on groundwater reservoirs of Saveh Plain. The 7 stations in the plain were selected for the monthly rainfall data. In this research, the DROUGHTs were examined for CZI, ZSI, MCZI, and SPI indices using DIP software and for the time scales of 3, 6, 9 and 12 months. The groundwater level drawdown in Saveh aquifer was approximately 31.86 meters during the 22 years of 1992-2014. The data for the wells was taken into account during two 10-year periods (1991-2001 and 2001-2011). Considering 5-year periods, we concluded that in the period of 1991-1996 a good regression was obtained and the drawdown was very slow. However in the next 5-year period a steep slope was detected in the regression which was followed by the same or slightly steeper slope in the next period (2001 to 2011). This was assessed as the consequence of unauthorized and uncontrolled exploitation of groundwater through wells. In a review of GROUNDWATER QUALITY using AqQa software the Piper diagram indicated calcic facies in the study area and the Durov diagram showed a sudden increase in total dissolved solids and a close to bicarbonate type. This can be due to the formations concerned, the leakage from an underlying semi-confined aquifer, or mixing with another source which requires further reviews.
