Abstarct: With increasing population growth, climate change and increasing industrial activities, the optimal use of border waters to meet the needs of communities, is essential. Identifying and evaluating available water resources and proper planning for harvesting these valuable resources can improve the condition of the watershed and the inhabitants of the watershed. Identifying water supply and consumption sources is the first step in managing the water resources of that basin in priority. Due to the lack of information with appropriate time and place distribution in border areas for various reasons such as impassability or lack of sufficient ground observation stations, the implementation of this step is challenging. Today, the science of remote sensing, along with the techniques available in the GIS, has made it possible to monitor and evaluate the water resources of such basins. In the present study, the Qarahatikan river basin, and in particular the Qarahatikan village basin, which is located in northeastern Iran and neighboring Turkmenistan, was investigated. To identify and evaluate the basin, IMERG-Final satellite precipitation data, ERA5 reanalysis temperature data and evapotranspiration data of the global evaporation model of Amsterdam GLEAM were used. Using runoff inlet data to the basin, runoff created in the basin with the help of Justin's experimental Equation, precipitation data, transpiration evaporation and downstream environmental requirements as runoff outlet from the basin, water available in the basin in months Different were calculated. This information was provided to experts along with vegetation laxyers, land use, soil type, slope and direction and the network of waterways, and they determined the priorities of water harvesting and consumption in the three sectors of agriculture, animal husbandry and watershed management. Expert opinions were analyzed using hierarchical analysis method and Expert Choice software. The results showed that the first priority for water consumption in the region is the construction of greenhouses and increasing the area under orchards and sheep fattening are the second and third priorities, respectively. Poultry farming is the last priority in this region.
