In order to manage water resources, determination of the quantity of recharge in groundwater is a necessary issue. Many variable parameters such as soil characteristics, topography, amount of rainfall, evapotrairation and the depth of water table are effective factors on the recharge of groundwater. Cumulative Rainfall Departure (CRD) model, which is based on the groundwater balance, due to its simplicity and minimum need for random parameters, is widely used to estimate for groundwater recharge. This model needs the data including: monthly rainfall, water table statistics, aquifer storage coefficient, inflow and outflow statistics of the aquifer. Moreover, water quality changes during infiltration through the different geological layers. So analyzing the effect of artificial recharge plans on the changes in quality of groundwater is of importance. The aim of this research was to estimate the quantity of recharge in the plain of southern Shahreza and to analyze the effect of artificial recharge plans on the changes of groundwater quality in the selected areas. The quantity of natural recharge in the southern Shahreza plain area was simulated using CRD model. Also, the water table was simulated by this model for each month. The results showed that the trend of simulated water table follows the measured data. The differences between the simulated and measured diagrams for water table may be attributed to the factors such as lack of data on unauthorized wells, over extraction in the authorized wells and the lack of measurement of water table in the area at the same time. The quantity of natural recharge in the southern Shahreza plain was equivalent to 34.61% of rainfall. More than 60% of this amount was occurred in the western and southern areas of the plain. The average rainfall in the Southern Shahreza plain is estimated 204 mm per year and the area of this plain is around 2510 (km 2 ), the annual amount of the groundwater basin fed by rainfall was estimated about 177.2 million cubic meters. It should be noted the optimizing the method with minimizing root mean square errors between the simulated and measured water table data was done. For better understanding of groundwater conditions under artificial recharge facilities, increase in water table under this facilities and their radius of influence were simulated using the infiltration equations and Hantush model. Maximum water table rise (22 m) and maximum radius of influence (600 m) were related to Kohrouyeh project. The soil texture and high permeability in this area are the main reasons for the obtained results.
