Cover Story: Knowledge of crop water use in irrigated agriculture is important for farmers, water districts, and policy planners. This is important in Arizona because of drought and shortage from the Colorado River. Current estimates don’t reflect changes in plant varieties, agronomy, and irrigation. A remote sensing study was conducted to determine water use for cotton, durum wheat, and alfalfa. Evapotranspiration (ET) models were implemented over the Central Arizona Irrigation and Drainage District for 2008. ET was assessed for 137 wheat, 183 cotton, and 225 alfalfa plots. The models were the Satellite-Based Energy Balance for Mapping Evapotranspiration with Internalized Calibration (METRIC), the Two Source Energy Balance (TSEB), and Vegetation Index ET for the US Southwest (VISW). Model averages, excluding surface evaporation, were 742 mm for wheat, 983 mm for cotton, and 1427 mm for alfalfa. View this paper
