Abstract (2. Language): 
Drought is a normal, recurrent feature of climate. Though it has been assumed rare and random event, but it occurs in all climatic regions. In this study, data on monthly rainfall of 9 stations located in a province of Iran, in the period of 27 years were prepared and investigated. Because of the special situation and topographic characteristics of Iran, the climate is different. The average annual rainfall of about 224 to 275 mm is mentioned. After simulation and validation of models, allowable water exploitation and drop of water level in the aquifers was considered. In this research 3 stations were (D1, D3, D4) has been defined as separate unites for models. Analysis and Hydrographs of plains, show that one of the zones had less downward slope in comparison with others, because of the location, absorbed wells and collecting system which feed the plain and slightly less affected by drought. Steady exploitation of each station from 2 to 20 cubic million, shows the drop of 0.43 m of aquifer level (from 0.93 m to 0.5 m), which is considerable amount in comparison with current well arrangement (ten percent of water drop).
