Abstract: The IHACRES model has been widely shown to be successful in modelling rainfall-runoff
processes in a variety of environments including mountainous regions. Our objective was to determine if
landscape features could be used to determine model parameters that could successfully be transferred to
ungauged basins and the uncertainty of such estimates be simultaneously assessed. Here we report
preliminary results where calibrated model parameters from a variety of mountain watersheds are compared
to basin area, drainage density and other attributes derived from digital elevations models. These results
indicate that some model parameters exhibit a relation to basin characteristics. However, noise in these
relations limits the usefulness of the model for estimating hydrologic response at ungauged mountain basins.
Keywords: ungauged basins, pluvial watershed, landscape attributes
