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.

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.

Modified Blaney-Criddle method — an empirical approach to estimate potential evaporation using air temperature [PDF]

open access: yesProceedings of the International Conference on Mine Closure, 2009
Potential evaporation (PE) or potential evapotranspiration (PET, ETo) is one of the fundamental elements in the hydrologic cycle. The Blaney-Criddle (B-C) method is the simplest approach for estimating PE as it requires only temperature data for input.

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 ...
