摘要: This study presents a comprehensive sensitivity and uncertainty assessment of important input parameters on the Alpine3D modeled snow water equivalent (SWE) for two different alpine catchments. Horizontal resolution DEM grid, station coverage several meteorological quantities were modified. Decreasing horizontal from 25źm to 1000źm leads 10% higher SWE. Modifications in spatial stations influences SWE up 20%. within some plausible ranges lead changes 30%. The results demonstrate that uncertainties are general same range as typical measurement scenario spread GCM-RCM ensemble runs. 30%.Alpine3D
