SUPPLEMENTARY INFORMATION:

I. Information About the Project/Document

    There is growing concern about the potential effects of climate 
change on water resources. Watershed modeling was conducted in 20 
large, U.S. watersheds to characterize the sensitivity of streamflow, 
nutrient (nitrogen and phosphorus) loading, and sediment loading to a 
range of plausible mid-21st century climate change and urban 
development scenarios. The study also provides an improved 
understanding of methodological challenges associated with integrating 
existing tools (e.g., climate models, downscaling approaches, and 
watershed models) and datasets to assess the potential effects of 
climate change and urban development on stream flow and water quality. 
Study sites were selected to represent a range of geographic, 
hydrologic, and climatic characteristics throughout the nation. 
Watershed simulations were conducted using the Soil Water Assessment 
Tool (SWAT) and Hydrologic Simulation Program--FORTRAN (HSPF) models.

[[Page 13875]]

    Simulation results illustrate a high degree of variability in the 
response of different streamflow and water quality attributes to 
climate change throughout the nation. Results also illustrate 
sensitivity to methodological choices such as different approaches for 
downscaling global climate change simulations and use of different 
watershed models. This understanding may lead to improvements in how 
existing models and datasets can be used to assess climate change 
impacts on watersheds.
    This report presents a summary of simulation results. The report is 
technical in nature but results are of broad interest to water and 
watershed managers, urban or regional planners, government officials, 
and scientists and engineers interested in the potential implications 
of climate change on streamflow and water quality in different regions 
of the nation.
