Areal evapotranspiration estimation using several alternative formulations of the CRAE hypothesis

Abstract

Accurate estimation of ET from large irrigated areas is essential for sustainable development of land and water resources. The CRAE hypothesis offers a convenient technique for areal ET estimation using only regularly recorded meteorological data. In this study several alternative models for areal ET are derived from the fundamental CRAE hypothesis and their performances assessed using data of the Everglades Agricultural Area, Florida. Results indicate the feasibility of obtaining acceptable estimates of areal ET from irrigated land using the CRAE concept.
