Primary Application Category:climate change  
Secondary Application Category:calibration, sensitivity, and/or uncertainty analysis 
Watershed Description:431,000 km^2 Upper Mississippi River Basin (north central U.S.; outlet assumed at Grafton, Illinois) 
Calibration Summary:1989-97 annual r2/E = .91/.91 monthly r2/E = .75/.67 
Validation Summary:1980-88 annual r2/E = .89/.86 monthly r2/E = .70/.59 
General Comments:A regional climate model (RegCM2) was used to downscale GCM (HadCM2) climate projections and a "reanalyzed climate" to SWAT. A sensitivity/error analysis was performed for both contemporary climate (1990-99) streamflows and the overall hydrologic balance; the largest error (18%) was found to have occurred with the GCM model (relative error contributions of SWAT and RegCM2 were found to be quite small). An analysis of a future climate (2040-49) indicated that a 50% increase in streamflow would occur at the assumed Upper Mississippi outlet at Grafton, Illinois.
