Effect of Wells on Aquifer's Water Table

Abstract

In this paper quantitative simulation of Bahar aquifer located in Hamadan province is done using Modflow program. In the first stage of this study hyaulic flow model of groundwater run and in continue the region wells include observation and pumping wells 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 in order to maximum confidence achievement the area simulation according to recharge and withdrawal carried and extracted graphs about water budget and drawdown have been analyzed. According to clarify the status of the water table aquiferat the end of the simulation the judgment about the appropriateness or not of the current level of withaw from the aquifer was determined that respect to water table awdown and negative result of water budget table the current withaw operation is not appropriate and in ought years the aquifer will be in danger of high awdown.
