Abstract
Water is the absolute necessity of every living being on the earth and in the current context, saying that it is a scarce resource will not be a far-fetched statement. The problem of evaporation of water from open agricultural fields is taken into consideration in this work. A simulation of evaporation in an open field and when a semi-permeable membrane is used to cover the field is performed in an open-source simulation software named OpenFOAM. The simulation is performed for total evapotranspiration considering a mean temperature for the month of May at Prayagraj, India. It is seen from the result that the semi-permeable membrane has intensely decreases the evapotranspiration rate from the surface of the agricultural land even in the hottest month. The amount of water that was prevented from evaporating ranged from 75–84% at a different time of a day/month/year. Thus, semipermeable membrane is found to reduce evapotranspiration rate and also regulates the temperature.
