Evaporation: Transcript

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 The rate of evaporation is depended on the.

Water vapor CONDENSES to form clouds. Clouds become very heavy before beginning to PRECIPITATE. Precipitation collects in rivers, lakes, and oceans. The sun warms ocean water…. Daily Operations and Accounting. Daily estimates are used for operations and accounting at certain reservoirs, but not all. Estimates are typically based on pan evaporation measurements or reference evapotranspiration. David Tarboton . Utah State University. dtarb@usu.edu. 435-797-3172. Outline. Lake level fluctuations.
