Register now for Evapotranspiration: Challenges in Measurement and Modeling from the Leaf to the Landscape Scale and Beyond.

An important part of the hydrologic water cycle is plant water use (transpiration) and evaporation from earth and ocean surfaces. Together, these two processes are called evapotranspiration. Scientists and engineers studying climate, ecosystem productivity, water use, and many other topics are interested in understanding, modeling, and measuring evapotranspiration.

The international symposium is organized by the American Society of Agricultural and Biological Engineers (ASABE), and co-chaired by Southern Research Station (SRS) research hydrologist Devendra Amatya and Weyerhaeuser Company research hydrologist Jami Nettles with SRS research hydrologist Ge Sun as Technical Committee Chair.

The symposium will bring experts, researchers, practitioners, and water managers together to explore and discuss advances in the understanding of evapotranspiration processes, interactions, and changes at all scales, as well as the ecological and socioeconomic implications of evapotranspiration. Advances in the basic science, technology and applied methods of measuring and modeling evapotranspiration will also be discussed.

The symposium will be held on April 7 – 10, 2014, at the DoubleTree by Hilton Raleigh Brownstone-University, in Raleigh, North Carolina. Attendees must register for the meeting. Non-ASABE members presenting at the symposium are entitled to register at the lower ASABE member rate by contacting Sharon McKnight (

Over 200 participants are expected, and James Vose, project leader of the SRS Center for Integrated Forest Science  will be give the opening speech at the keynote session on the morning of Monday, April 7.

In addition to a number of special sessions and technical sessions, invited keynote, plenary, and lunch time session speakers will discuss lessons learned in measuring and modeling evapotranspiration across the globe. For more information about the keynote and plenary sessions and detailed technical program agenda, view a list of session titles and speakers (PDF). A symposium proceedings book with all accepted keynote, plenary, special, and general session abstracts will be distributed at the symposium.

Two field trips are offered on April 10. Participants can visit a watershed study of the environmental effects of intercropped switchgrass as a dedicated energy crop and loblolly pine, or visit an eddy flux system study of water and carbon cycling in a pine forest. Amatya and SRS research hydrologist Ge Sun are collaborators in these studies on Weyerhaeuser’s managed pine forests.
