Glacier retreat and permafrost degradation lead to alterations in the process regime of high mountain regions, increasingly promoting potentially hazardous natural phenomena, among them glacial lakes. These lakes are dammed by the glaciers themselves or their moraines and thus prone to abrupt drainage, termed Glacier Lake Outburst Flood. At the Goldbergkees, Hohe Tauern range (Austria), such a lake has evolved during the last decade as a consequence of terrain-induced processes and since then burst out repeatedly. Aim of this work is to investigate this lake in terms of its previous evolution to derive behavioural patterns for future prospects. The former was realised by means of different evaluation methods of photogrammetric data, which were subsequently matched with environmental parameters to infer on spatiotemporal patterns of relevant factors. In the course of a field campaign in summer 2016, the lake was first surveyed to enable a quantitative estimate of its volume. Furthermore, runoff data deriving from the gauging station at the outlet of the glaciers catchment was compared with meteorological parameters to deduce discharge behaviour and potential interactions with the lake. Past outbursts were analysed to draw inferences on possible trigger mechanisms, drainage routing and peak discharge properties and the relations between the particular process components, respectively. Scenario data of future glacier properties as well as geophysical exploration of underlying bedrock characteristics served as input for developing a simple topography-based model for lake evolution. Combined with the previous findings, potential future configurations and consequently valuations can be derived. The results both document past and suggest future lake growth associated with sustained probability of outbursts.
