بررسي روند تحول پتانسيل آب زيرزميني دشت هشتگرد در ده سال گذشته و علل آن

Dry periods in the recent years and unconditional usage of ground water without attention to its actual potential has been cased to enhance depletion of the Hashtgerd aquifer. The study of the Hashtgerd plain was conducted to show its negative effects. The current study is for past ten years periods (1369-1379). The presented article contains geology, meteorology and hydrology of the study area. With collected data from the respected organizations, analyses of ground water potential were performed. The results showed a 6.14 meter ground water depletion for the current period with an average of 30 million cubic meter depleted storage. Proposed recommendations are to control discharge of authorized wells, installation of water meters and to prevent discharge of unauthorized wells. Considering the geological and climatic conditions of the Kordan River with its 11 million cubic meter annual surplus water, artificial ground water recharge was proposed.
