One of the most important tools for water demand management is water and energy tariff changes. The aim of this effort was to study the level of groundwater in Mehran plain using the system dynamics method under different scenarios of energy carriers price changing. the conceptual model was designed, dynamic hypotheses were explained and simulation was performed. After calibration and verifying the model, the research purpose was evaluated in terms of applying 12 scenarios combining energy tariff increases and water tariff increases. According to the results the effect of changing energy tariffs on changes in aquifer volume and groundwater level was more than the change of water tariff. The results also indicated that the increase of water and energy tariffs could reduce harvest from the groundwater, and in all scenarios an increase in energy tariffs of 80 percent of the current tariff and increasing the surface water tariff of 50 percent of the current price and Performance of the Right to Supervision would have the greatest impact on the stopping of the decline in groundwater levels and its significant increase
