thumbnail New Evapotranspiration (ET) website in Nevada –USGS hydrologists typically measure evapotranspiration (ET) to help quantify water budgets. (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.) Developing accurate water budgets for a basin or region improves our understanding of ground-water flow systems. The Nevada Water Science Center has developed a web site (in progress) to consolidate information about ET. ET rates have been measured by USGS hydrologists in Nevada since the early 1960's. A clickable map shows locations where ET rates have been measured, allowing immediate access to data, photos, and location information.
