General Comments:The impact of using from 1 to 15 raingauges in both watersheds was evaluated for SWAT-predicted runoff, & nitrogen and sediment losses. The results indicate that a high density of rain gauges are needed in order to obtain accurate results (when comparing simulated output to measured data). The use of national weather service stations was found to be inadequate for both watersheds, most likely due to the sparseness of the stations. Extrapolation of the results to other watersheds/models is discussed.
