A Framework for Modeling Rock Glaciers and Permafrost at the Basin‐Scale in High Alpine Catchments

Since rock glaciers are believed to be more resilient climate change, water stores therein may become important reservoirs in future, particular dry regions, which currently rely on glacial runoff. In order estimate and evaluate the future runoff potential from permafrost glaciers, distributed models suitable for high Alpine catchments needed. An extension Glacier Evolution Runoff Model (GERM) include is presented here, compared established one dimensional (1D) physics-based model SNOWPACK. The new component introduced GERM treats as discreet depth layers a 1D column all grid cells, have bulk thermal properties calculated their constituents (ice, water, air, solid component). temperature evolution computed using heat conduction latent exchanges, modified by ventilation effects. Finally, we infer degradation. Ground variations both borehole measurements at three sites similar performances found. Differences between present amplitude of seasonal ground variations, with SNOWPACK having tendency slightly overestimate them, while underestimates them.
