Rational Use of The FAO Blaney‐Criddle Formula

Journal of Irrigation and Drainage Engineering - ASCE, 1986
The FAO Blaney-Criddle (FAO-BC) evapotranspiration equation was calibrated and tested against a Penman combination equation with local wind function and daily lysimeter measurements of alfalfa evapotranspiration. Agreement between the calibrated FAO-BC method and lysimeters was excellent for daily, weekly and monthly estimates when measured values for ...

Spatio-temporal Calibration of Blaney–Criddle Equation in Arid and Semiarid Environment

Water Resources Management, 2009
Estimates of reference evapotranspiration (ETo) are widely used in irrigation engineering to define crop water requirements. A major drawback to application of the FAO Penman-Monteith is the relatively high data demand which unfortunately, for many locations; such meteorological variables are often incomplete and/or not available.

Assessment of Blaney-Criddle Equation for Calculating Reference Evapotranspiration with NOAA/AVHRR Data

Water Resources Management, 2014
Reference evapotranspiration (ET0) data are desirable for assessing crop water requirements and irrigation needs. A large number of methods have been developed for assessing ET0 from meteorological data. In several places of the world, the existing network of weather stations is insufficient to capture the spatial heterogeneity of this variable The ...

Pendugaan Evapotranspirasi Menggunakan Metode Hamon, Cristainsen, dan Blaney-Criddle Modifikasi dengan Perbandingan Acuan Metode Penman-Monteith [PDF]

Evapotranspirasi menjadi faktor penting dalam perancanaan sistem irigasi, konservasi, dan manajemen sumber daya air. Perhitungan laju evapotranspirasi dengan teknologi modern seperti penggunaan satelit Moderate Resolution Imaging Spectroradiometer (MODIS) telah banyak dilakukan.

Elevation ? A Bias Error in SCS Blaney Criddle ET Estimates

Transactions of the ASAE, 1984
ABSTRACT ELEVATION adjustments for evapotranspiration estimates are investigated. Bluegrass and alfalfa data from throughout the Western states are used to determine an elevation adjustment for the SCS Blaney Criddle formula. Six to ten percent upward adjustment per 1000 m altitude increase above sea level is required for calculated evapotranspiration.

Estimating Evapotranspiration with Water-Production Functions or the Blaney-Criddle Method

Transactions of the ASAE, 1982
ABSTRACT SEASONAL evapotranspiration (ET) for cotton (Gos-sypium hirsutum L.), corn (Zea mays LJ, alfalfa (Medicago sativa LJ, and barley (Hordeum vulgare LJ can be estimated with either the Blaney-Criddle method or county yield data with a water-production function.

A Watershed Evapotranspiration Prediction Using the Blaney-Criddle Approach

Transactions of the ASAE, 1985
ABSTRACT THE Blaney-Criddle approach was applied to produce a watershed-scale estimate of evapotranspiration. The application was tested on seven Coastal Plain watersheds ranging in size from 15.7 to 334.3 km2 with mixed forest, crop, and pasture use. Seasonal and annual empirical consumptive use coefficients are presented for the test drainage areas ...
