abstract = {Parameterization of physically based and distributed
hydrological models for mesoscale catchments remains
challenging because the commonly available data base is
insufficient for calibration. In this paper, we parameterize
a mesoscale catchment for the distributed model
HydroGeoSphere by transferring evapotranspiration parameters
calibrated at a highly-equipped headwater catchment in
addition to literature data. Based on this parameterization,
the sensitivity of the mesoscale catchment to spatial
variability in land use, potential evapotranspiration and
precipitation and of the headwater catchment to mesoscale
soil and land use data was conducted. Simulations of the
mesoscale catchment with transferred parameters reproduced
daily discharge dynamics and monthly evapotranspiration of
grassland, deciduous and coniferous vegetation in a
satisfactory manner. Precipitation was the most sensitive
input data with respect to total runoff and peak flow rates,
while simulated evapotranspiration components and patterns
were most sensitive to spatially distributed land use
parameterization. At the headwater catchment, coarse soil
data resulted in a change in runoff generating processes
based on the interplay between higher wetness prior to a
rainfall event, enhanced groundwater level rise and
accordingly, lower transpiration rates. Our results indicate
that the direct transfer of parameters is a promising method
to benefit highly equipped simulations of the headwater
catchments},
