Abstract
ABSTRACT Aquifer artificial recharge is one method of restoring groundwater supplies and storing extra water to compensate for losses. In this regard, this research simulates the Dammam aquifer in the MODFLOW code in GMS software. The other objective is to simulate the effect of artificial recharge on groundwater levels in the Dammam-confined aquifer in Iraq. Modeling was done by specifying boundaries and initial conditions. The model was calibrated for steady and unsteady conditions. The calibrated model was utilized to predict groundwater levels in 2030 and assess five artificial recharge scenarios with different proportions of injection water. The water source in the simulation recharge model was excess water from sand-washing plants. The effect of these scenarios was evaluated on the available monitoring wells. The artificial recharge by injecting 60% of the daily excess water into 15 and 51 wells showed a maximum groundwater level increment of about 17–30%, respectively.
