Three types of objective functions were tried and the error function which give equal weight to equal proportional errors was noted to be the best objective function to use in determining appropriate parameter values of the model. The model was modified such that daily hydrologic data can be used. For a two-year simulation period, the model simulated streamflow was able to account the daily variation of the observed streamflow to a certain degree.
