Bankruptcy Method in Reduction of Groundwater Resources conflicts and Aquifer Balancing (Case Study: Haji Abad Aquifer)

In recent decades, increasing water demand in Iran has resulted in excessive water usage, specially groundwater. Due to the increase in aquifer water usage, groundwater management should considerate to meet consumers needs and achieving a fair benefit in addition aquifer sustainability and future needs. This study aimed to manage and reduce water usage of Haji Abad aquifer in Hormozgan province. first, Groundwater simulation model was calibrated and validated by MODFLOW software and then, the new operation wells discharge values were calculated by using the cooperative method (bankruptcy) and these values were entered into the simulation model and the results were compared with the current situation. In this study, five bankruptcy methods proportional (P), Constrained Equal Award (CEA), Constrained Equal Loss (CEL), Talmud (Tal) and Piniles (Pin) are used to manage operation wells discharge, The annual discharge values of the operation wells are claimer demand and the amount of groundwater recharge which calculated by the simulation model in each polygon are the available water. In these five methods, groundwater head increased and overall aquifer status improved relatively well. Finally, the Bankruptcy Allocation stability index (BASI) for five methods was calculated and compared.compared.
