Abstract | A Fortran version of the Stanford Watershed Model, without snowmelt, was used to generate streamflow data on two small agricultural watersheds. Five years of recorded data were used to 'calibrate' the model after which 5 additional years were generated using the model parameters developed for the first period. A variety of sensitivity runs were made to gage the effectiveness of different model parameters. The four most important parameters were the interflow index, the infiltration index, lower zone storage index, and an infiltration - evaporation index for applying a seasonal variation to infiltration.
