Abstarct: Forecasting the water table fluctuations and changes in groundwater storage is of great importance in their efficient management. Rukh aquifer, with an area of about 2182 km2, is enclosed from the north side to the Neyshabur basin, from the east side to the Sarjam and Torbat Jam basins, and from the south side to the Azghand, Rivosh, and Zaveh basins. Rukh aquifer has the largest share in supplying drinking water to Faiz Abad city, subordinate villages and also a part of drinking water to Torbat Haidarieh city, which necessitates conducting studies in this important aquifer. For this purpose, the numerical model of the aquifer was prepared to predict the behavior of the aquifer in different scenarios and in line with the management of that valuable aquifer using MODFLOW computer code. The general groundwater flow direction is from the east to the west of the aquifer. The average hydraulic gradient in Rokh aquifer is 0/003. Therefore, the underground recharge and discharge area of the aquifer are from the Neyshabour and Ataieh area, respectively. The results of calculated water balance in the area indicate a reservoir deficit of about 27 Mm3/y, due to increasing groundwater drawdown during enhancing agricultural usage. The calibration of the model was done baxsed on the 12-month data of the 2018-2019, and the statistics of the 2019-2020 data were used to validate it. The hydraulic conductivity, storage coefficient, precipitation infiltration coefficient and return flow water of the aquifer in the numerical model were 8 to 32 m/d, 6 to 7%, 10%, and 20%, respectively. The calculated numerical model of the area in steady state condition was sensitive to the recharge parameter and hydraulic conductivity. Also, in the unstable state, the sensitivity of the model is in relation to the recharge, hydraulic conductivity and specific storage, respectively. The calibrated and validated numerical model has been used to predict the behavior of the aquifer in different scenarios, such as the continuation of the current conditions, checking the level of the groundwater level with a 10% decrease and increase in the withdrawal from the exploitation wells along with a 5% decrease and increase in the recharge amount. baxsed on the results of the numerical model, the continuation of the current process without applying the reduction conditions of water withdrawal will cause an increase in the drawdown of the reservoir. The results of applying discharge and recharge scenarios showed that the best scenario would be to reduce the discharge flow rate of each well by 10%.
