THE LONG-TERM IMPACT OF KABODARAHANG’S THERMAL POWER PLANT ON GROUNDWATERAmin Sarkhosh and Saeid Shabanlou
The purpose of this study is quantitative simulation of Kabodarahang aquifer located in the Hamadan Province of Iran with area of 3470 square kilometers.In this study the groundwater hydraulic flow model was run and then observation and pumping wells data entered into the software and finally all of piezometers data input to the software for calibration of the model. The tools used in this study are PMWIN (Processing MODFLOW for Windows) software package for hydraulic simulation of groundwater flow and PEST computer code for calibration of data. After collecting the useful data from relevant organizations in Hamadan Province and providing the geographical maps and GIS maps and all of essential data for run the software, the calibration of the model was performed, then we run the software and extracted output files include contour maps, graphical maps, graphs and Water Budget tables. Next, the plant quantitative model was simulated and run independently. Then, the run model integrated into the main model and graphs related to the drawdown were investigated by applying the plant boundary conditions. The results showed that the plant activities effects on the aquifer level are significant so that at the end of 2012-2013 water year there is a drawdown about 2.5 m around the power plant.
