AMUNDSEN

The physically based hydroclimatological model AMUNDSEN (Alpine MUltiscale Numerical Distributed Simulation ENgine) has been designed to specifically address the scenario-capable modelling of hydrological and climatological processes in mountain regions. The model includes the following modules:

  • computation of topographic parameters from a DEM
  • simulation of shortwave and longwave radiation fluxes including consideration of topography with shadows and cloudiness (Corripio 2003, Greuell et al. 1997)
  • parameterization of snow albedo depending on age and temperature (Rohrer 1992)
  • modelling of snowmelt with either an energy balance model (Strasser et al. 2008) or an enhanced temperature index model considering radiation and albedo (Pellicciotti et al. 2005)
  • modelling of the forest snow processes interception, sublimation and melt unload (Liston and Elder 2006) as well as consideration of the effect of the trees on the micrometeorological conditions at the ground (Strasser et al. 2008, 2011)
  • simulation of gravitational redistribution of snow (Gruber 2007)
  • calculation of scenario input data by means of a stochastic weather generator (Strasser 2008)
  • computation of actual evapotranspiration (Allen et al. 2005)
  • simulation of wind-induced redistribution of snow (Warscher et al. 2011)
  • parameterization of glacier retreat geometry changes (Huss et al. 2010)
