Evaluating Potential Evapotranspiration Models For Ahar Region

In order to determine consumptive use of water for plants, management of irrigation and other agricultural studies potential evapotranspiration is requird. However, commonly used prediction methods have not been corrected for regions. For determining the best model for culculation of potential evapotranspiration in Ahar station, evaporation pan potential evapotranspiration values were compared applying different methods.results showed that Turc, Thornth-waite, Christianseen-Hargreaves (RA) and Blaney-Criddle methods have best correlation with pan potential evapotranspiration values than other, applicable technigus.
