Service Description: Maps of estimated water use (2005), population density, housing density, precipitation, and potential evapotranspiration per 8-digit Hydrologic Unit Code (HUC08) were created as apart of the DOE/ORNL NSD Resource Assessment (<http://nhaap.ornl.gov/nsd>). 

Descriptions of data are provided in Hadjerioua et al (2013), An Assessment of Energy Potential from New Stream-reach Development in the United States, Initial Report on Methodology. Report ORNL/TM-2012/298. January 2013.Water use estimates (2005) per county were obtained from USGS: Kenny, J.F., Barber, N.L., Hutson, S.S., Linsey, K.S., Lovelace, J.K., and Maupin, M.A., 2009, Estimated use of water in the United States in 2005: U.S. Geological Survey Circular 1344, 52 p.(<http://pubs.usgs.gov/circ/1344/>). 

County level shapefiles and population density was obtained through the US Census Bureau (<http://www.census.gov/geo/maps-data/data/tiger.html>). Water use estimates were joined to county shapefiles through common county identifier. Water use was summarized by 8-digit Hydrologic unit codes using area-weighted averages of county-level data [Spatial Analyst (zonal statistics as table)]. 

Population density was obtained through the US Census Bureau (<http://www.census.gov/geo/maps-data/data/tiger.html>). Popluation density was summarized by 8-digit Hydrologic unit codes using area-weighted averages of county-level data [Spatial Analyst (zonal statistics as table)]. 

Precipitation and potential evapotranspiration per 12-digit HUC was obtained from Wollock, D. (2003) Hydrologic landscape regions of the United States, US Geological Survey Open-File Report 03-145, Reston, VA: <http://water.usgs.gov/GIS/metadata/usgswrd/XML/hlrus.xml>. Precipitation was summarized by aggregating 12-digit hydrologic units into 8-digit hydrologic units.
