Effect Of Floating Azolla Cover On The Evaporation Of Open Waters In Jordan

In this experiment two plastic containers are used, both are filled with water, and one is covered with the Azolla plant. The effect of introducing Azolla cover is investigated. The experiment is done under real weather conditions in the city of Amman, Jordan, for 15 days. The water temperature of both containers and the solar radiation of the site were measured. The result shows that during the day the water temperature in the Azolla container was always less than the container with water directly exposed to the sunlight. It was concluded that the water evaporated from the uncovered container was greater by 23% than the other container.
