Evapotranspiration (ET) is the combined loss of water in the form of evaporation from the soil surface and transpiration from the plant through the stomata. Evapotranspiration which is the sum of transpiration through plant canopy and evaporation from soil, plant, and open water surface, can be the largest component of the hydrologic cycle. Improved techniques are needed for accurate quantification of ET on a field, watershed, and regional scale to enhance efficient use of water resources and protect the environment and water quality. Accurate quantification of ET is crucial in water allocation, irrigation management, evaluating the effects of changing land use on water yield, environmental assessment, and development of best management practices to protect surface and groundwater quantity and quality.
