In this study, using Modis images and wets pass model, the value of evapotranspiration for the northern Karun basin was estimated monthly from 2000 to 2014. The value of correlation coefficient for the obtained evaporations was R2 = 0.72. This model was calibrated and verified for different regions with different parameters. Data from 2000 to 2009 were used for calibration and data from 2010 to 2014 were used for validation of the model. The value calculated 0.54. In this study, with a review of climatic parameters of temperature, precipitation, evaporation during the period before the dam construction and after that, the effects on the microclimate of the area is investigated. Finally, to study the changes caused arising from the creation of a dam on the amount of evapotranspiration using the monthly images of Modis during the studied statistical period, the classification of images was done and the amount of changes were calculated. The results showed that the amount of evapotranspiration in the basin after the construction increased and its changes with distance from the dam in some months also has been increased.
