One of the main causes of the water crisis in Iran is the lack of a well-organized framework for providing information about water balance components and water uses. Therefore, the use of a water accounting framework is a necessity. The purpose of this study is to show the capacity of the WA + framework for the preparation of water accounts in Rokh-Neishaboor basin, which is presented in four main sections: Organizing information, reporting, planning and assessing. The Organizing information section includes the collection of data from various sources, including of satellite measurements and modelling. The planning section include scenario development that in this study, two scenarios of reducing aquifer withdrawals were considered which were in line with the approvals of the Supreme Water Council. Reporting was done by completing various WA + sheets for three years inculding wet, normal and dry under real and scenario conditions. The assessing section was presented by the indicators for each sheet and for real and scenarios conditions.The results of the water situation in the basin showed that in Rokh-Neishaboor basin, a sharp drop in aquifer storage occurs every year. Also, about 80% of rainfall in the basin evaporates and becomes unavailable. Finally, the findings of using scenarios to reduce aquifer withdrawals (according to aquifer restoration plan( showed that if the aquifer withdraw was equal to renewable water, the annual aquifer deficit would reach zero and its reserve would increase.
