| description | The catchment of the river Inn is located in the Swiss and Austrian Alps. In
the frame of the flood forecasting system "HoPI"
(<i>Ho</i>chwasser<i>p</i>rognose für den Tiroler <i>I</i>nn), the
Austrian part of the river Inn and its tributaries are covered within a
hybrid numerical model. The runoff from the glacierized headwaters of the
south-western Inn tributaries is calculated using the Snow- and Icemelt Model
"SES" which utilizes a spatially-distributed energy balance approach;
within SES, the accumulation and melting processes for snow, firn, and ice
are considered. It is of great importance that such a type of model is used
in the simulation of alpine areas since in these regions stream flow is
influenced by the accumulation and melt of snow and ice and snow-free
glaciers have also the potential to increase or even induce flood flow. For a
prototype of the forecast system, SES was calibrated using the snow depletion
of a glacier, but later, following the first results during the operational
mode, the model was recalibrated and validated using remotely-sensed data
covering all 13 glacierized catchments. Using the final snow-parameter
setting, a simulation run of 15 hydrological years without any state
corrections achieved overall agreements between observed and simulated snow
cover ranging from 68% to 88% for all individual catchments. Runoff was
calibrated and validated using the data from three different gauges. A
parameter set, including both validated snow and runoff parameters, was
applied for the modelling of a fourth gauged catchment and also achieved
accurate results. This final unique parameterization was transferred to the
remaining, ungauged watersheds. |
