Supporting Data

Data files in support of the analysis presented in the report titled Evaluating Sustainability of Projected Water Demands under Future Climate Change Scenarios are identified below. Also included is an appendix that illustrates the calculations performed for a single county.

Water use data are based on the 2005 water use survey, prepared by the US Geological Survey, and available on the Internet at: http://water.usgs.gov/watuse. Please cite the USGS report as a source for 2005 values: Kenny, J.F., N.L. Barber, S.S. Hutson, K.S. Linsey, J.K. Lovelace, and M.A. Maupin (2009), Estimated use of water in the United States in 2005, U.S. Geological Survey Report, Circular 1344.

For the Tetra Tech report, projections were made for 2030 and 2050. See report text for assumptions used for 2030 and 2050 projections. Note that the USGS does not make future projections of water use.

Model-predicted climate data for the 21st century were obtained using the ClimateWizard tool, developed by Evan Girvetz (http://www.climatewizard.org). This tool, in turn, uses the set of downscaled results for the 21st century from 16 global climate models, developed by Edwin Maurer and colleagues (http://www.engr.scu.edu/~emaurer/data.shtml). The citation for the downscaled data set is: Maurer, E. P., L. Brekke, T. Pruitt, and P. B. Duffy (2007), Fine-resolution climate projections enhance regional climate change impact studies, Eos Trans. AGU, 88(47), 504.
