Soil moisture-based approach for estimating actual evapotranspiration

One of the most important words on planet Earth is stated as water. Concerning its availability, requirement, generation, transportation, and losses, the study of water is important. This water can be in various forms as well as losses. The present study concentrates on calculating the actual evapotranspiration from a small piece of land using various basic details like temperature, field capacity, wilting point, and instantaneous soil moisture. The study aimed to understand the dependence of actual evapotranspiration losses on soil moisture. It was found that the AET calculated using the Bergstrom method gives satisfactory results. In support, actual evapotranspiration calculated from soil moisture of hydra probe (ground data) and satellite data both justifies the values to true environmental condition. With lots of future scope for research, the experiment done was found enough satisfactory. This research may help get an idea about actual evapotranspiration from a limited land area with less meteorological data available daily, weekly, monthly, or yearly.
