Abstract

The simulation results from physically-based hydrology and erosion models contain uncertainty, and it is therefore desirable for it to be reduced. Two methods are considered : one which relies on improved parameter set selection, and a second which derives physical parameters from observed hydrographs. Both methods are compared with a blind application of the model and observed data. The results suggest that, while both methods may be successful in reducing the variation in model output, the coincidence with the observed data deteriorates
