Rainfall and deep percolation of irrigation are the most important sources of recharge in Khatoon-Abad plain, Kerman province, Iran. Artificial recharge is a practical strategy to increase the storage capacity of groundwater in drought condition. Modeling of groundwater flow for a steady-state period (April 2017 to October 2017) and an unsteady state period from October 2012 to August 2019 was simulated in monthly stress steps. In this study, root mean square error and coefficient of residual mass have been used to evaluate the results of calibration and verification process obtained by PMWIN software. Moreover, two strategies of artificial recharge were incorporated for considering the water table fluctuations. The results show that artificial recharge by direct injection of water into the aquifer prevents evaporation, runoff and outflow as runoff from the plain and increases the aquifer water availability. In different scenarios, the different amounts of recharge were applied to the aquifer, and the simulation results showed that the effect of recharge in the study period varies from 3 km to more than 7 km.

降雨和灌溉的深层渗透是伊朗克尔曼省 Khatoon-Abad 平原最重要的补给来源。人工补给是增加干旱条件下地下水储存能力的实用策略。对稳态时期（2017 年 4 月至 2017 年 10 月）和 2012 年 10 月至 2019 年 8 月的非稳态时期的地下水流量建模，按月应力步长进行模拟。在本研究中，均方根误差和残留质量系数已被用于评估 PMWIN 软件获得的校准和验证过程的结果。此外，考虑到地下水位波动，采用了两种人工补给策略。结果表明，通过将水直接注入含水层进行人工补给可防止蒸发，径流和流出作为平原的径流，增加了含水层的可用水量。在不同的情景下，对含水层施加了不同的补给量，模拟结果表明，研究期间补给的效果从3公里到7公里以上不等。
