Contribution to EGU General Assembly 2016
This year’s EGU General Assembly has passed and we presented a number of topics in 4 different sessions.
In a session with numerous outstanding talks on Mountain Climates on Wednesday, Joseph Shea presented initial results from an analysis of glaciological and hydrological sensitivities in modeling in the Hindukush Himalaya region.
On Thursday, Walter Immerzeel opened the session on debris covered glaciers with a solicited talk, summarizing our recent efforts in quantifying mass changes on the debris covered glaciers. During the same row of talks Jakob Steiner looked at the spatial and temporal evolution of ice cliffs and lakes in the Langtang catchment in the recent decade.
The round of talks was followed by a poster session with 20 submissions specifically on the topic of debris covered glaciers, underlining the increased attention the issue has received recently. Philip Kraaijenbrink presented his work on the monitoring of glaciers using unmanned aerial vehicles. Pascal Buri presented some progress on the distributed modeling of ice cliff backwasting in the catchment. Evan Miles provided insight into the temporal change of supraglacial lakes and how to extract this information from Landsat imagery. He also presented recent work on deriving surface roughness oft he glacier with photogrammetric analysis. The contribution to this session was rounded off by Pascal Egli’s work on deriving debris thickness from remotely sensed temperature data. Jakob Steiner also presented some insights from analysis of the development of a large alluvial fan in the Langtang catchment in a session on sediment transport in pro-glacial environments.
The week ended with Tobias Bolch presenting Silvan Ragettli’s recent work on mass balance change in the Langtang catchment during the last decade.
