Hydrogeologic and Hydrochemical Investigations of Esfahak Aquifer-Tabas

The Esfahak plain is located in the south of Tabas and the west foot hill of Shotori mountain. The present study is an attempt to provide the necessary water resource for the Tabas coal mine. The thickness of the sediment deposits in this plain is reaching up to 450 m. In this study, based on the field observations, geophysic, and chemical analysis of water, the shape and placement of the bed rock are determined. The iso-piezometric and iso-salinity maps, have also been prepared and the hydrogeologic studies of the aquifer has been performed. The results show that in the position of bore hole No. 38, water is injected to the aquifer sediments through the bed rock. Moreover, the dynamic, static, and economic resources of the aquifer have been estimated.
