Abstarct: The aquifer can be unconfined aquifer and confined aquifer laxyers are formed. To evaluate groundwater flow in a are used multilxayered aquifer lithology logs, water table and piezometric levels, pumping tests, and hydrochemical characteristics. The results of the geophysical data and well logs drilled in the Plains Aquifer, a multilxayer has been detected. In the East, the aquifer is unconfined aquifer laxyer and the middle part of the aquifer to the west end, in addition to the unconfined laxyer is a laxyer of extended confinement. Fluctuations in observation wells (boreholes drilled in the Unconfined laxyer) shows a decreasing trend with an average water table has dropped 0.49 meters a year. Fluctuations in piezometers (boreholes drilled in confined laxyers) also decrease the loss rate show of 0.7 meters per year Piezometric. Equipotential lines in the Unconfined laxyer suggests that this laxyer of the southeastern edge of North and East and the West, supply is Discharged. Confining laxyer is fed from the South East and the West is Discharged. Investigation showed that the type of water quality data in the Unconfined laxyer in the South East, bi-carbonate and elsewhere aquifer is infinite clorite. Type bi-carbonate type of water is confined in laxyer. The electrical conductivity of the Unconfined laxyer in the South East to 335 µ/cm in well Asdaghi and 4800 µ/cm in parts of West laxyered looks. Confined laxyer in the laxyers of 818 µ/cm at the entrance to more than 2000 µ/cm laxyer in the output laxyer is reached. Similar type of underground water and electrical conductivity of the confining laxyer to the Unconfined laxyer represents the southeastern part of the area is confined to a laxyer recharge
