Crop Water Use Studies
Abstract
Two studies of mountain meadow water use have
been conducted recently along the Little Laramie River
and in the Upper Green River Basin of Wyoming.
The objectives of the studies have been to develop
technical data and calibrate models for evapotranspiration
of mountain meadow vegetation. Field
measurements of water use and climatic data were
taken in the Little Laramie River study during 1979
through 1982 and in the Upper Green River study
during 1983 through 1985. Water balance lysimeters
were used to measure water use in each study with
those in the Little Laramie River Valley being placed
on a line across a valley while those in the Green
River Basin were placed along a 20 mile stretch of
Horse Creek. Results of the field measurements and
analyses of data show a high rate of vegetative water
use, with values near those of pan evaporation rates.
Measurements show a tendency for actual water use to
vary depending on available water supplies and
irrigation practices. Estimation of maximum water
use can be accomplished through use of a number of
different models, however, local calibration is
necessary.
