Abstract

Recognation of performance and prediction of how Climate Change and human activities affect the Groundwater resources is necessary in Groundwater resources management. Groundwater resources play an important role in supplying domestic, agricultural and industrial water in semi arid regions. In such regions, increasing population and water demand along with the Climate Change, causes negative effect on Groundwater guality and quantity. In this research important factors influncing Groundwater quality and quantity changes has been investigated. In the first step, GMS10. 05 software was used for determining and simulating characteristics of Mahabad aquifer, in western Iran. After calibration and validation of model, we researched about effective factors influncing Groundwater change. To this aim, results was obtained without human activity factors in the first run. In this condition average of Groundwater level was obtained to be 3 meters higher than the Groundwater level observations. Investigating the constraction of dam as an anthropogenic activity factor showed that the dam construction causes Groundwater level to be 1. 11 meters lower than the pervious condition. We then predicted the Groundwater EC and SAR using GEP as a function of Groundwater level. We concluded that anthropogenic activities in comparison to the natural changes are the primary force which demolishes the Groundwater level and guality and changing the irrigation of Groundwater class to C3S1. The result of this study is applicable in developing criteria for adaptation Groundwater resouce management in future.
