| General Comments: | SWAT Simulations for a portion of the 20th Century (1963-2000) were performed using precipitation data generated from nine GCM models. The ninie-member ensemble was found to perform quite well overall, although simulations using output from low resolution GCMs resulted in large differences in streamflow & other hydrological indicators relative to observed values. The most accurate predictions were obtained using the only high resolution GCM included in the ensemble. Statisical tests indicated the GCM-predicted streamflows were serially uncorrelated at all lags, formed unimodal distributions, and can be used to assess annual UMRB streamflows. |
