Abstract: The transpiration part of the coupled Shuttleworth–Wallace model was compared to the data measured using the heat balance sap flow method on sweet cherry trees planted in Hungary. The model was validated under various weather conditions. Appropriate consistency was found between the transpiration part of two source, the output of the Shuttleworh–Wallace evapotranspiration model and the measured sap flow data. Although the model underestimates transpiration on cloudy and rainy days as well as on high vapour pressure deficit days, it is suitable for quantifying the water loss of intensive sweet cherry orchards.
