Abstract

Intensive measurements of evapotranspiration during two growing
seasons show that large scale advected sensible heat is a significant
source of energy to evaporation from irrigated crops in southern
Idaho. Even though the site of the study was several miles from the
boundary of the irrigated areas and the surrounding desert, measured
latent heat flux exceeded net radiation by as much as 25%. Inversion
conditions near the surface of well-watered crops having complete cover
were typical throughout the day in mid- summer. The results emphasize
the importance of developing a meaningful concept and measure
of potential evapotranspiration for irrigated areas in arid regions and
for the development of reliable methods of predicting the evapotranspiration
from various crops throughout the season as the stage of
maturity and crop cover changes under these arid, climatic conditions.
