Due to the increasing water needs as a result of increasing consumption in various sectors of drinking, agriculture and industry, the need to provide appropriate planning to provide instructions for the use of available and available water resources is of great importance. Based on this study and computation from the balance sheet, the real potential of the alluvial aquifer is determined and the permitted operation is planned. In this regard, the first step is to prepare a groundwater balance for exploitation in real and future conditions. Due to the increase in the number of exploitation wells, by calculating the effective parameters in the balance equation (plains inputs and outputs) for the water year 94-93, reservoir changes were calculated to be -39.59, which shows a negative balance of increasing water level Groundwater is the plain and its reservoir fraction. Also, comparing this number with the fraction resulting from changes in groundwater storage in the Varamin plain, resulting from the hydrograph of the aquifer unit, it is clear that the calculated components of the balance are with acceptable accuracy and can be used as a good estimate of parameters. Aquifer drainage and feeding in Varamin plain should be used to build mathematical model and aquifer management.
