Reading: Applied Hydrology Sections 3.5 and 3.6. With assistance from Dan Siegel and Marcy Litvak. Evaporation. What is evaporation?. Evaporation is the process in which a liquid changes to the gaseous state at the free surface, below the boiling point through the transfer of heat energy .

Estimates are typically based on pan evaporation measurements or reference evapotranspiration. Liquids have molecules moving around in them. . Temperature is the average kinetic energy (which depends on the speed) of these molecules.. Some are moving. faster than others!. If they are moving fast enough, at just the right angle,. How is evaporation measured?. How is evaporation estimated?. Reading: Applied Hydrology Sections 3.5 and 3.6. With assistance from Dan Siegel and Marcy Litvak. Evaporation. What is evaporation?. How is evaporation measured?. A process whereby liquid water is . converted to water vapour. and . removed from the vapour surface.. Evaporation consists of 2 components i.e. The energy component and the aerodynamic component. The energy component is responsible conversion of liquid water to water vapour.
