Abstract
Water is a vital source of growth and development in human societies. In dry and semi-arid areas like most areas of Iran, because of lack of surface water, groundwater resources are used. This research studies the process of extraction of groundwater resources from the six main watersheds of Iran during the years of (1982-2018) and predicts the rate of harvesting of these resources by 2025. For this purpose, the Time series model was used in the ARIMA method. The results showed with current management that the rate of harvesting of these resources in the future will increase in the most of the basins and this will endanger the availability of these resources and human life. Pricing of water resources used for agriculture, the installation of the smart meters and the sustainable management of groundwater resources are recommended to improve the predicted state.
