Evapotranspiration Studies in Nevada

Science Center Objects

Evapotranspiration (ET) is the process that transfers water from land surface to the atmosphere as evaporation (or sublimation when below freezing) from open water, soil, and plant canopies and as transpiration by plants. ET is measured by scientists for many different reasons. Hydrologists from the Nevada Water Scientist Center (NVWSC) typically measure ET to help quantify water budgets. Developing accurate water budgets for a basin or region improves our understanding of groundwater flow systems. ET rates have been measured by USGS hydrologists in Nevada since the early 1960’s.

The NVWSC ET web site is a work in progress. The purpose of the web site is to consolidate information about completed and ongoing ET studies. The overview map shows locations where ET rates have been measured. Click on a diamond for information about the site.

Note: NWIS archived data are available only for studies completed after 2006.
