Summary of Success: 2013 Presentations

Ogallala Aquifer Program workers met in Amarillo, Texas in March of 2013 to summarize what they have discovered recently during the course of their work. These videos run from ten to thirty minutes and are a good way to learn what is new.

In the News

Ogallala Aquifer Program and Scientists Recognized   Ogallala Aquifer Program recognized for its role in water conservation by the Water Conservation Advisory Council and ARS scientists recognized by ARS-USDA and the Soil and Water Conservation Society.   

Production Systems Priority Area Accomplishments for 2011   Annual accomplishment statements for this priority in 2011 are reported herein.   

Upcoming Events

There are currently no upcoming events scheduled.


Spatial Interpolation of Daily Evapotranspiration (ET) Data in the Texas High Plains   Commonly used interpolation (inverse weighted, spline, and kriging) methods and one new method (machine learning with optimization algorithm(s)) were evaluated for mapping reference ET in the Texas High Plains. Thin-plate spline models increased accuracy of the daily ET maps.  

Statistical and spectral approaches to automate hot and cold pixel selection for surface energy balance based evapotranspiration mapping   A novel statistical-spectral methodology for the selection of hot and cold end member pixels is developed to make the application of single source energy balance models more robust, and successfully applied. Results indicated that the proposed methodology performed better than existing methods.   

About the Ogallala Aquifer

“The Ogallala Initiative is a project funded by the United States Department of Agriculture-Agricultural Research Service (USDA-ARS). The Initiative provides permanent funding for several research projects on water conservation for the Ogallala Aquifer through a consortium between USDA-ARS, Kansas State University, Texas A&M University, Texas Tech University, and West Texas A&M University.”
