Simulating the influence of snow surface processes on soil moisture dynamics and streamflow generation in an alpine catchment

Michael Lehning, Nander Wever, Francesco Comola

The assessment of flood risks in alpine, snow-covered catchments requires an understanding of the linkage between the snow cover, soil and discharge in the stream network. Here, we apply the comprehensive, distributed model Alpine3D to investigate the role ...
