Practical prediction of actual evapotranspiration

Irrigation Science, 1980
A simplified method of estimating actual evapotranspiration of crops during an irrigation interval in which soil-moisture deficits occur is presented. With some simplifying assumptions, a relation is developed between a crop-dependent critical leaf water potential, potential evapotranspiration rates, and the fraction of available soil-moisture at which

Alternate corrections for estimating actual wetland evapotranspiration from potential evapotranspiration

Wetlands, 2006
Corrections can be used to estimate actual wetland evapotranspiration (AET) from potential evapotranspiration (PET) as a means to define the hydrology of wetland areas. Many alternate parameterizations for correction coefficients for three PET equations are presented, covering a wide range of possible data-availability scenarios.

An R package for modelling actual, potential and reference evapotranspiration

Environmental Modelling & Software, 2016
Evapotranspiration (ET) is a vital component of the hydrological cycle and there are a large number of alternative models for representing ET processes. However, implementing ET models in a consistent manner is difficult due to the significant diversity in process representations, assumptions, nomenclature, terminology, units and data requirements.

COMPARISON OF ACTUAL AND CROP EVAPOTRANSPIRATION FROM GRAPE VINES

Acta Horticulturae, 2000
Maximum 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.

An experimentally derived model for actual evapotranspiration

Agricultural Meteorology, 1971
Abstract 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 ...

Model Etforest for Calculating Actual Evapotranspiration

1979
ABSTRACT 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.

Pan Evaporation, Potential and Actual Evapotranspiration

Journal of Applied Meteorology, 1967
Abstract A formula for estimating the evapotranspiration rate from temperature and relative humidity data is given. Results of some tests of the accuracy of the equation indicate that it is better than other equations based on a similar number of variables.

Explicit and Recursive Calculation of Potential and Actual Evapotranspiration

Agronomy Journal, 2007
The explicit combination method (ECM; Penman, 1948) to calculate potential evapotranspiration (ETp) is a physically based model using standard climatological data. It is based on an assumption regarding the temperature and humidity at the evaporating surface that is not made in a recursive combination method (RCM; Budyko, 1958).
