Investigation and Quantitative Modeling of Groundwater (Case study: The Plain of Neyshabour)

Inhabitants of the arid climate has led to greater use of groundwater. On this basis because of the importance of water resources, the quantity of groundwater in the plain of Neyshabour during 2002 to 2008 was evaluated. Visual MODFLOW software was helpful in this regard. The results showed that hydrodynamic coefficients are relatively high in plain of Neyshabour. This property can be very effective in the fields of artificial recharge projects. Also due to the high correlation between observed and calculated data from the model calibration, results are acceptable in all observation wells. Studies showed that groundwater in the plain of Neyshabour has dropped highly due to the excessive travel, drop in water levels in different regions according to different feeding and discharging aquifer.The map of stone floor level shows that the context of the postal and the mountain aquifer Neyshabour is high and concave mode. Feeding rate calculated in the Binalood lower elevation are more than other areas due to seasonal flooding into this area are flowing of the highlands. The results showed a continuing trend of regional drainage wells in some areas, so groundwater quality and quantity is reduced.
