Abstract

 Groundwater is one of the most important sources of fresh water needed in the world. In this study, climate data of precipitation, temperature and evaporation in seven meteorological station; were been used at 20-year period (90-1370). The research method is a causal manner. The correlation and regression statistical methods were used to study variation of precipitation on aquifer water levels. Average of total rainfall monthly of catchment was calculated using of data from the 1430 cell of 240 maps (20 years x 12 months), respectively. Review of iso-drop maps show that underground water level has dropped in some areas up to 44 meters. On the other hand, with respect to maps of groundwater movement, this result can be applied a firm management on removal of groundwater; because the water is moving around the aquifer to its center due to law relating to container. So you increase the harvest by palm Central Plains wells, wells sharply against a plain edge and causing them to shrivel. Our study showed a quite direct relationship between precipitation with water level but relationship of temperature and evaporation with water balance is reversed. Therefore the process of consumption must be formulated in such a way that the amount of water fed by rainfall could be accountable for the discharge.
