- The loss of water from the soil both by evaporation and by transpiration from the plants growing in the soil.
- The total water loss due to the transpiration of vegetation plus the evaporation from the soil; higher climatic temperatures result in a higher evapotranspiration rate.

- water lost from the combined surfaces of soil and plant to the atmosphere. Originates from evaporation, water lost from the soil to the atmosphere and transpiration water lost through stomata or plant surfaces to the atmosphere.
