Résumé / Abstract

A geographical information system (GIS) was applied to the hydrological modelling in the Glatzbach River basin which is located very close to Grossglockner in the Hohe Tauern mountain range of the Austrian Alps. A hydrological model based on TOPMODEL (Beven et al., 1995) was adopted and used to model the hydrological response of the basin. To generalize TOPMODEL further provision was made to include a snowmelt routine, the calculation of potential evapotranspiration, hydrological routing and an infiltration algorithm into the model. As an additional part of this study the model components have been evaluated against field measurements wherever data were available. Then the generalized model was calibrated against a 50-day time series of measured runoff for the year 1989. This model calibration was evaluated for the years 1990 and 1996. A comparison between observed and simulated runoff on an hourly basis illustrates that they match well in distribution and volume for this high mountain basin using the generalized TOPMODEL version.
