Abstract
The climate parameters data for more than forty years for Karbala meteorological stations were studied
.The results show good evidence of climate change indicated by the remarkable decrease of the average
means annual rainfall in the studied stations, with the remarkable increase of the average mean annual
temperature. MODFLOW program is applied. GIS, 3D spatial analyst is used to prepare future planning
to drill more water wells. The impact of the climatic change on the groundwater was obvious in
decreasing the water table as studied in the unconfined aquifer in Karbala – Najaf area. The Dibdiba
aquifer in this basin represents the shallow aquifer which recharged mainly from rain water. Since this
source is scarce, the aquifer gains its water slowly in a rate less than the rate of losing it by both
evaporation and abstraction wells. The designed model and the water budget calculations confirm this
state that the aquifer is worn out and predict that within the year 2014 several sites were depleted
especially the eastern parts of the Dibdiba aquifer.
