METRIC model results of monthly ET images for the ORMVA Tadla
interpolation procedure. ET
r
values represent the ET rate expected from a well-defined
surface of full-cover alfalfa and are computed using the point weather data from the
weather stations listed in Table
13.1
. The resulting monthly ETmaps provided the basis
for review and further analyses. For the ORMVA Tadla (Fig.
13.5
), ET is shown in
mm/month for each 30-m pixel for the entire irrigated area and for the pilot irrigation
schemes targeted by the World Bank-funded irrigation improvement project.
