The Hydrological Simulation Program FORTRAN (HSPF) model was calibrated for the South Nation watershed located in Eastern Ontario. Three nonlinear automatic optimization techniques were applied and compared: Gauss-Marquardt-Levenberg (GML) method, Random Multiple Search Method (RSM), and Shuffled Complex Evolution method developed at the University of Arizona (SCE-UA). The best GML, RSM, and SCE-UA variable values beyond which objective function improvement is insignificant were suggested. It was found that more than one parameter set is able to maintain the model in a calibrated state which reflects correlation among model parameters and equations. The lowest v...
