An input-output model allows the interaction between the supply and demand sides of an economy to be examined. It can also provide decision makers with information on the total production of sectors as well as required resources. In this paper, we used an input-output model to manage water use and estimate the total water use for various economic sectors in Iran's North Khorasan Province (INKP). Initially, the province's economy was disaggregated into 19 sectors and the regional input-output table was estimated using the Cross-hauling Adjusted Regionalization Method. Then, using linear programming, the basic input-output model was transformed into an improved input-output model having the ability to choose among alternative technologies for allocating water to sectors. To compensate for the water shortage by selecting alternative technologies and assessing their impact on the total cost of the system as well as the production, three scenarios for managing the supply side and one scenario for reducing the final demand of the most water-consuming sector (managing the demand side) were analyzed. The results showed that the agriculture sector is always required to use less water-consuming and more expensive technology to compensate for about 161 million cubic meters of water to keep the total production unchanged.
