DS-777 Average Annual Actual Evapotranspiration, 2000 to 2009, in inches estimated from the Soil Water Balance (SWB) Model for the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

The water-budget components geodatabase contains selected data from maps in the,
"Selected Approaches to Estimate Water-Budget Components of the High Plains, 1940
through 1949 and 2000 through 2009" report (Stanton and others, 2011). Data were
collected and synthesized from existing climate models including the Parameter-Elevation
Regressions on Independent Slopes Model (PRISM) (Daly and others, 1994), and the
Snow accumulation and ablation model (SNOW-17) (Anderson, 2006),and used in
soil-water balance models to compute various components of a water budget. The
methodologies used to compute the averages and volumes for the data in this
geodatabase are slightly different for different components and models.
