| Zusammenfassung |
| Physically-based water balance models require a realistic parameterisation of
land surface characteristics of a catchment. Alpine areas are very complex with strong
topographically-induced gradients of environmental conditions, which makes the
hydrological parameterisation of Alpine catchments difficult. Within a few kilometres the
water balance of a region (mountain peak or valley) can differ completely. Hence, remote
sensing is invaluable for retrieving hydrologically relevant land surface parameters. The
assimilation of the retrieved information into the water balance model PROMET is
demonstrated for the Toce basin in Piemonte/Northern Italy. In addition to land use,
albedos and leaf area indices were derived from LANDSAT-TM imagery. Runoff, modelled by
a water balance approach, agreed well with observations without calibration of the
hydrological model.
Keywords: PROMET, fuzzy logic based land use classification, albedo, leaf area index |
