Introduction In the present study, the Qarah Tikan river basin in particular the subbasin of Qarah Tikan Village has been studied. This is located in the northeast of Iran and among the basins without ground station data. IMERG-Final satellite precipitation products, ERA5-Land reanalysis temperature and GLEAM evapotranspiration were used to evaluate the basin. Materials and Methods The water balance equation was used to calculate the available water. GLEAM global data (Shiklomanov, 2000) used for actual evapotranspiration and environmental needs obtained by the Lyon method were considered as outputs. The inflow to the basin and the precipitation, which was obtained from IMERG-Final-V06 (Huffman et al., 2019) satellite data were considered as the inputs. To calculate the environmental needs, the monthly runoff of the basin is required for which Justin's experimental method was used. for Justin's experimental method, monthly runoff, precipitation, and temperature of IMERGFinal satellite data and ERA5-Land were used. By using ArcMap and DEM the slop and area of the basin was produced. Results and Discussion The results of evaluating monthly temperature data showed that these data have a high ability to estimate the temperature and is reliable in remote areas where there is no weather station. According to the comparison of satellite precipitation data and ground stations, although they do not have high accuracy in estimating precipitation, but they have a good correlation and estimate precipitation with appropriate accuracy. Precipitation in 3 stations is underestimated and overestimated in 2 stations. Based on the long-term average, the annual rainfall of the basin is about 225. 9 mm. a study of evapotranspiration data from the GLEAM shows that the long-term annual average is about 194. 4 mm, which peaks in the spring due to greater access to water and rising temperatures. About 86% of the basin rainfall in the evaporation process is out of reach. The annual inflow to the basin was about 15. 9 Mcm and the annual runoff from rainfall in the basin according to the Justin method was about one Mcm. The annual environmental need was determined to be about 7. 5 Mcm. The annual water available is 11. 8 Mcm. Conclusion To meet the demand of the agricultural sector in summer and control winter and spring floods, planning for the construction of a storage dam should be on the agenda. So, the output of the basin will be adjusted. This emphasizes the importance of remote sensing and GIS in the study of water resources in ungauged basins without proper ground station statistical data.
