ASSESSMENT OF UNAUTHORIZED WELLS EFFECT ON BAHAR AQUIFER USING MODFLOWEghbal Khorami, Saeid Shabanlou and Hosein Rahimi
In this paper quantitative simulation of Bahar aquifer located in Hamadan province was done using Modflow program. In the first stage of this study hydraulic flow model of groundwater was run and in the region all wells were included have observation and pumping wells were imported to the software and after importing all of wells and piezometrics elevations and defining of pumping discharge of wells and calibrating of data collected was done in order to have maximum confidence achievement the area simulation according to recharge and withdrawal carried out and extracted graphs about water budget and drawdown have been analyzed. According to clarify the status of the water table aquifer at the end of the simulation the judgment about the appropriateness or not of the current level of withdrawl from the aquifer was determined.
