Model Etforest for Calculating Actual Evapotranspiration
1979ABSTRACT The model calculates actual evapotranspiration from potential evapotranspiration, with leaf area, root development, and soil water as limiting factors. The evapotranspiration is divided into transpiration, evaporation from soil surface, and evaporation of intercepted precipitation in canopy.

COMPARISON OF ACTUAL AND CROP EVAPOTRANSPIRATION FROM GRAPE VINES
Acta Horticulturae, 2000Maximum crop evapotranspiration (ETc) represents the evapotranspiration rate for a crop with little or no reduction in transpiration due to a water limitation. However, ETc is dependent on the irrigation method and management because of the influence on soil evaporation.

Transactions of the ASABE, 2012
With the world population expected to increase by 3.7 billion people by 2050, it is anticipated that the additional food and fiber required to feed future generations will impose greater pressure on freshwater resources. Approximately 70% to 80% of global freshwater withdrawal is for irrigation, and more than 40% of food is produced on irrigated land ...

Distributed Estimation of Actual Evapotranspiration Through Remote Sensing Techniques
2007Evapotranspiration (ET) is one of the main water balance components, and its actual value appears to be the most difficult to measure directly. Therefore, the choice of reliable models capable of predicting spatially distributed actual ET represents a drought monitoring fundamental aspect.

An experimentally derived model for actual evapotranspiration
Agricultural Meteorology, 1971Abstract Experimental data from several different climatic regions were used to develop a statistical model for actual water loss rates from land surfaces. The actual evapotranspiration rate was considered to be influenced by the amount of available water in the soil and by meteorological and plant conditions which determine the potential ...

Observing actual evapotranspiration using smartphone sensors
Evapotranspiration plays a key role in the terrestrial water cycle, climate extremes and vegetation functioning. However, the understanding of spatio-temporal variability of evapotranspiration is limited by a lack of measurement techniques that are low-cost, and that can be applied anywhere at any time.Adriaan J.
