Testing the performance of ice thickness models to estimate the formation of potential future glacial lakes in Austria

The emergence of glacial lakes is a significant consequence global climate change in high mountain regions. Recent developments ice thickness modelling combined with high-resolution glacier surface data led to the generation approaches simulate ice-free bedrock topography below current glaciers and detect potential bed overdeepenings (GBO) that may form into future lakes. We simulated subglacial Austrian Alps using two different models. Glaciers study area differ significantly from investigated previous studies on because their general small size location often restricted cirques. aim this estimate number Austria. tested performance models for an environment dominated by are under stress change. Modelling results compared evolved since periods derived geophysical surveys. Results show differences model concerning total volume GBOs. modelled GBOs overestimated, have past. Most valley type glaciers, even though most types. This does not match existing dominantly found ascertain approach performs better large less well glaciers. Intersecting runs indicates up 42 new within 23 Austria covering 2 km2.
