Abstract
Over-exploitation from Goharkuh plain aquifer, southwest of Zahedan, resulted in water table drawdown. In order to assessing the effect of artificial recharge, numerical model of groundwater flow of the aquifer was developed. Well loges, hydrogeologic parameters, pizometric heads and results of pumping tests were used in this study. The flow model is well calibrated and used to simulate future water level fluctuations. Steady state condition has been considered in January of 2003 because of low fluctuation in groundwater level in this period. The Sensivity analysis related to a few parameters and verification for period of February of 2004 to February of 2005 has performed. The results indicate that groundwater level is reducing in Goharkuh plain aquifer. Maximum drawdown occurs in the east part of the aquifer. Aquifer reaction has been assessed by definition of different scenarios to identify the best location for artificial recharge. Based on the result, the north part of the aquifer (close to pizometer P9) is the best location for performing artificial recharge.
