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.

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 ...

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 ...

Spatial modelling of reference evapotranspiration using adjusted Blaney-Criddle equation in an arid environment

Hydrological Sciences Journal, 2013
Abstract The Blaney-Criddle (BC) temperature-based equation is used in areas where the complete weather data to estimate reference evapotranspiration (ET0) by the Penman-Monteith FAO-56 (PMF-56) standard model is complex. In this study, the BC equation was first tested and calibrated against the ET0 values computed by the PMF-56 method using data from ...

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.

Estimation of FAO Blaney-Criddle b Factor by RBF Network

Journal of Irrigation and Drainage Engineering, 2000
This technical note presents the application of a Radial Basis Function (RBF) network to estimate the FAO Blaney-Criddle b factor. Tabular b values are given in the United Nations Food and Agriculture Organization Irrigation and Drainage Paper Number 24.

PENETAPAN EVAPOTRANSPIRASI POTENSIAL BERDASARKAN METODE HOLDRIDGE DAN BLANEY-CRIDDLE DI PULAU LOMBOK

Journal of Soil Quality and Management
Pulau Lombok termasuk kategori pulau kecil dengan luas sekitar 4.738,7 km² (Iskandar, 2008), sehingga tingkat kerentanannya terhadap perubahan iklim lebih besar dibandingkan pulau-pulau besar. Salah satu metode dalam mencari ETo yang sering digunakan adalah metode Blaney Criddle dan Holdridge. Penelitian ini menggunakan metode deskriptif.

Monthly spatial calibration of Blaney–Criddle equation for calculating monthly ET_o in south of Iran

Irrigation and Drainage, 2008
AbstractThe Penman–Monteith equation is the most common equation for estimating reference crop evapotranspiration (ETo). However, this equation needs full meteorological data, but few meteorological stations with complete meteorological data exist in Fars province, in the south of Iran.
