Senay 20130626 raster digital data Data Series 777 Reston, VA U.S. Geological Survey https://pubs.usgs.gov/ds/777 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. The Purpose of this geodatabase is to present selected raster data from the Water-Budget-Components report.

To fill in data in the area that became active following the boundary modifications, an Arc GIS 9.3 tool called "NIBBLE" was used. NIBBLE fills in the values of the no data cells with the values of neighboring cells. 2011 Sharon L.

The average annual raster was computed by taking the average of the 10 annual rasters cell by cell using the mean function in ESRI Arc Info GRID software. 20110712 Natalie A.

Austin TX 78754 USA (512) 927-3565 (512) 927-3590 nhouston@usgs.gov 7:30 am - 4:30 pm Central time zone In the Stanton and others (2011) report, the authors used this raster to compute average annual actual evapotranspiration and volume for each of the eight states that make up the High Plains (Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming), and for each of the three commonly defined regional zones (northern High Plains, central High Plains, and southern High Plains). The average annual actual evapotranspiration in inches was computed using a tool called zonal statistics in Arc GIS 9.3.1. Areas where the High Plains aquifer does not exist (no data) were not included in these computations. Data were rounded to the nearest tenth of an inch. The average annual volume of actual evapotranspiration in million acre-feet was computed by multiplying the average annual actual evapotranspiration in inches by the area in acre feet of the zone and then dividing by a million. Areas in acre feet for the zones are defined as follows: Colorado 8,523,000 Kansas 19,745,000 Nebraska 41,379,000 New Mexico 5,963,000 Oklahoma 4,735,000 South Dakota 3,106,000 Texas 23,209,000 Wyoming 5,183,000 northern High Plains (NHP) 61,655,000 central High Plains (CHP) 31,428,000 southern High Plains (SHP) 18,759,000 2011 Natalie A.
