Erratum to: Evaluation and calibration of Blaney–Criddle equation for estimating reference evapotranspiration in semiarid and arid regions [PDF]

open access: yesEnvironmental Earth Sciences, 2015
Penman–Monteith (FAO-56 PM) equation is suggested as the standard method for estimating evapotranspiration by the International Irrigation and Drainage Committee and FAO. On the other hand, the Blaney–Criddle (BC) temperature-based equation is an alternative and simple method compared with the FAO-56 PM equation.

Estimating the potential evapo-transpiration and crop coefficient from climatic data in Middle Delta of Egypt

open access: yesAlexandria Engineering Journal, 2013
There are many empirical and theoretical equations to estimate the value of the potential evapo-transpiration (PET) under certain weather conditions. The relation between PET and climatic factors has the greatest role in the development of such equations.

Estimación de la evapotranspiración a partir de datos satelitales para la región de Alto Beni, Norte de La Paz

open access: yesRevista de Investigación e Innovación Agropecuaria y de Recursos Naturales, 2021
La evapotranspiración (ET), resulta de un proceso simultáneo de evaporación y la transpiración. En una superficie de referencia, que ocurre sin restricciones de agua, se denomina como evapotranspiración del cultivo de referencia (ETo).

Forecasting daily reference evapotranspiration using the Blaney–Criddle model and temperature forecasts

open access: yesArchives of Agronomy and Soil Science, 2015
ABSTRACTAccurate daily reference evapotranspiration (ETo) forecast is essential for real-time irrigation scheduling. An attempt was made to forecast ETo using the Blaney–Criddle (BC) model and temperature forecasts in this study. Daily meteorological data for the period 2000–2014 at five stations in East China were collected to calibrate and validate ...
