Neural computing modeling of the reference crop evapotranspiration

open access: yesEnvironmental Modelling and Software, 2012
Reference crop evapotranspiration (ET"o) estimation is of importance in irrigation water management for the calculation of crop water requirements and its scheduling, in rainfall-runoff modeling and in numerous other water resources studies. Due to its importance, several direct and indirect methods have been employed to determine the reference crop ...

Similarity and difference of potential evapotranspiration and reference crop evapotranspiration – a review

Agricultural Water Management, 2020
Abstract Potential evapotranspiration (ETp) and reference crop evapotranspiration (ETo) differ in their developments, concepts, equations and application fields, however, many researchers have mixed the utilization of the two terms. Thus, it is necessary to clarify the terms to guide their proper usage.

Reference crop evapotranspiration determined with a modified Makkink equation

Hydrological Processes, 1998
A modified version of the Makkink equation is shown to be a suitable alternative for Penman's formula for the determination of the crop reference evapotranspiration Eref that is used in the so-called crop factor approach. Makkink's equation requires solar radiation and temperature data only. Since 1987 the Royal Netherlands Meteorological Institute has

Comparison of various methods for estimating reference crop evapotranspiration [PDF]

open access: yes, 2004
The reference crop evapotranspiration (ET0) was estimated for three locations of Bangladesh using the standard Penman-Monteith (P-M) method as recommended by the Food and Agriculture Organization of the United Nations (FAO). The same was also estimated using four other emperical methods and compared with the standard method.

Forecasting of reference crop evapotranspiration

Agricultural Water Management, 1993
Abstract The first step in the determination of irrigation water requirements for use in project planning, design, and operation commonly involves the prediction of the reference crop evapotranspiration. This paper presents a simple mathematical model for forecasting reference crop evapotranspiration at three stations in California that represent ...

Reference Crop Evapotranspiration from Temperature

Applied Engineering in Agriculture, 1985
MEASURED lysimeter evapotranspiration of Alta fescue grass (a cool season grass) is taken as an index of reference crop evapotranspiration (ETo). An equation is presented that estimates ETo from measured values of daily or mean values of maximum and minimum temperature. This equation is compared with various other methods for estimating ETo.

Estimating Reference Crop Evapotranspiration with ETgages

Journal of Irrigation and Drainage Engineering, 2009
Three years of daily reference evapotranspiration measured by atmometers ( ETg ) were compared to the values computed from the ASCE standardized Penman–Monteith equation ( ETr ) using co-located me...
