Working group meeting at Jamtalhütte

Working group meeting at Jamtalhütte

These two days were used to create a bigger picture of research already existing and planned in the LTER Jamtal. The excursion lead to a great viewing point for dicussing the longterm evolution of the catchment partly covered by glaciers with all its geomorphological forms and processes. High runoff in the evening caused overspill at the water intake downvalley.

Grain size recording

Grain size recording

The grain size distribution of a number of test-plots was counted using the Bunte sampling method in addition to the regularely UAV based photogrammetric surveys of the glacier forefield. The test-plots were geolocated with DGPS and are visible in the orthofotos from the UAV surveys. Thus the transferability of surface roughness from areal high resolution point clouds and digital elevation models to actual grain size distribution at the surface will be tested and developed.
